13 lb bowling ball question

[morgothaod]

I have an injured wrist and am thinking about going from a 14 to a 13 lb ball. I know the core will be different because of that. Does having a generic core in the ball defeat the purpose of buying a pro performance bowling ball? I bowl with a 14 lb Brunswick Meanstreak Beatdown. Would my ball reaction differ and be inconsistent if I buy it in 13 lbs? From the big dot in the middle of the approach, I put my right foot in between the big dot and the dot that is to the right of it. I then walk straight and aim between the 2nd and 3rd arrow (So I don't throw a big hook). My ball speed is about 15 mph and the top of my backswing is pretty much in line with my butt lol.

Brunswick is one of the companies that do not just use a generic core in their balls under 14 lbs. At 13 lbs., the core will not be identical to the 14 lb. version, but it will be close in terms of rg and differential. You should be fine switching to a 13 lb. Beatdown.

Motiv uses the same core shape in every weight ball they make in a prodduct line. They VARY THE DENSITIES TO CHANGE THE WEIGHT. fOR EXAMPLE MY WIFES 10 POUND aSCENT PEARL HAS THE SAME CORE SHAPE AS MY 15 POUND aSCENT PEARL

But I think Motiv is the only company that does that. I've noticed that Roto Grip/Storm is NOTORIOUS for putting pancakes in their lower weight balls.

As you know, DV8 is a Brunswick company. My Misfit does not use a generic weight.

generi cores are ok , just stayaway from pancakes

I can't see spending the money for a generic core. That being said many company's do the same core just investigate and find what's right for your game ;)

Before you decide on a ball, bowlingball.com is a great site to check out. It lists in a drop down menu if the core on the lower weighted bowling balls is the same or different. But as people have mentioned, generic core shouldn't make a huge difference. Definitely stay away from pancake cores though.

You should also check out the balls' web sites. The RGs/Diffs can be quite different in the lower weights. I think most balls are reviewed/rated at their 15# weight. Pay attention to the specs for the weight you want. in order to get the numbers you like, you may have to go to a different brand/ball line.

[edit] for example, the Tropical Breeze is listed as a lightly-reactive ball, and the Up Roar as a ball with more hook potential. But at 12lbs, they're practically the same in terms of numbers.
