Medium Rg mean medium oil use?

[Vince805]

So I have been doing some reading on bowling websites and stuff and from what I'm understanding is that medium Rg balls are meant for medium oil conditions? And low Rg are heavy oil and more aggressive cover stocks..... Now if this is true the new and upcoming DV8 ruckus fued is a medium Rg ball and claims to be very aggressive!!! And a VERY strong hooking ball... The most so from from dv8.....But meant for heavy oil lane conditions... So I'm a bit confused on the whole low and medium Rg thing.... Please help! :-)

The radius of gyration is an account of the location of the mass inside a given bowling ball and relates whether the ball mass is concentrated toward the center of the ball (low RG), toward the coverstock of the ball (high RG), or between the two points (medium RG).

Low RG balls will encourage a fast and early revolution rate and tend to pick up a strong roll pattern on the front end of the lane. Medium RG balls will pick up a strong revolution rate slightly later on the mid-portion of the lane and high RG balls will lope down the lane conserving energy for later use thereby picking up its strongest roll pattern on the back end of the lane.

Its not so much about the oil conditions but about how the ball is gonna overact as a whole a low RG is gonna start to hook a little earlier and a high RG ball is gonna get down the lane more and have a stronger backend reaction

Amen to that!

The most effect range of rg's for any bowler is determined by the bowler's style, not the lane conditions. Unless you have as much "hand" as the high rev pros, no ball will hook in the oil; they hook when the encounter friction, either past the pattern, or outside the pattern on a house shot. The rg measurement provides resistance to the ball revving up, and the ball cannot hook until it revs up. Bowlers with slower ball speeds should stock their arsenals with balls with medium to high rgs, while speed dominant players should gravitate toward balls in the lower to medium range.

In terms of specific lane conditions, look to the main elements of the ball that provide friction: cover, surface, and, to a degree, layout.

Are you sure about the part that is bolded?

The hook phase is the section where the path of the ball is not linear.

Assuming the ball does not have an effective 0 degrees of axis rotation, the instant the ball sees friction, the path is going to become non-linear.

That friction for most people will cause an increase in rev rate.
At the point where the ball has reached it's maximum amount of rev rate is where the ball transitions into the roll phase.

[RobLV1]

Yes, I'm positive about the bolded section. It has to do with Newton's First Law of Motion, the part that says, that an object in motion will continue at the same speed and direction until acted upon by an unbalanced force. That unbalanced force in bowling is a combination of the friction that the ball encounters from the lane surface in combination with the rotational energy applied by the bowlers release. The ball begins to hook when the friction becomes great enough primarily as a result of the ball reaching it's full rev potential (Moment of Inertia) that allows it to slow down enough that the rotational energy becomes equal to the forward directional energy, allowing the ball to hook. The phases of ball motion, in order, are: skid, hook, hook-out, roll, and roll out. The goal of every bowler is to get the ball to enter the pins at the point of maximum energy. That is the point were the ball first begins to roll. If the ball is still hooking as it enters the pins, the result is usually a solid nine pin (for a right hander), or worse yet, a 4-9 split. If the ball rolls too early and is beginning to lose energy as it enters the pins, the result is an eight pin, a weak ten, or an 8-10 split.

First off i want to thank everyone for the replies they have been very helpful....
but i quote what you said because i have been bowling since i was 12. and just did it for fun. im now 34 and just now paying attention to the more technical side of it all and trying to understand it. So i looked up my first bought high performance ball. it was a Columbia 300 action packed, a very low rg ball (aggressive ball) my next ball was a brutal nightmare, also a low rg ball (aggressive) and now my newest ball the storm byte, not a low rg ball. Now what i noticed from all my balls not including the Byte is that the best way i can describe it is that i have to put effort into getting the ball to hook. alot of moving around and different wrist positions to get more revs so the ball would hook where i needed it to....So when i first got my Byte i did that and didnt see a reaction like any of my other balls. So i went back to a style i used before i got all these high proformance balls, dont ask me what they were idk they were my dads old balls lol and wow!!! works perfectly. I dont have to move much at all. i can use that ball all night and make at most one adjustment mid way thorough the third game. and i dont have to but much effort and try to generate alot of revs for it to get down the lane and turn like ive never seen, except my brutal nightmare.
Now this may be a stupid question but would this mean im better off with med rg balls vs low to ultra low rg? I to have tons of revs and now a speed dom played. id say 15-16 mph and medium revs. If so would a dv8 ruckus fued fit my style as a brutal replacement?

I don't agree with the first bold section, but I do agree with the second bold section.

You appear to think the ball has to rev up to it's full potential and slow down to equalize the energy levels before that ball begins to hook.
It's my opinion that it is during this rev up, slow down activity that the ball is hooking.

If the ball is seeing friction, the crosswise component, (due to axis rotation) will cause the ball to deviate from it's original path.

If the ball doesn't rev up until it sees friction, then both hooking, and rev up / slow down are occurring simultaneously.

Thank you for posting that link. I just finished reading every word of it and learned more (a lot more) than I did searching around and reading different articles over the last month. Very good centralized location of a wealth of knowledge!
