Upside down drilling??

[Phonetek]

Last night at the bowling alley I noticed this guy who had a urethane burgundy Hammer drilled upside down. Other words the finger holes were where the thumb would be and vise versa. What was the point of doing this? The only thing I noticed is that when he threw it the hammer logo was visible when he threw it so you can see it spinning like when a left hander throws it. I can't imagine he did this merely for ascetic reasons. Wouldn't that completely screw up how a ball would react? I would think even worse especially if it was one of these newer cores?

Without seeing exactly what it was, most likely a full roller layout.

It just struck me as odd. I guess being at a bowling alley everyday I'm bound to see a lot of strange things. Some really stupid questions too. A lady asked if it was okay if she was to wear our bowling shoes without socks. I said "The person before you that had them on did the same thing and had some really cool looking purple and yellow foot fungus so knock yourself out." That was the end of that conversation and yes she wore socks.

Was it similar to Tom Smallwoods ball he used today? If so, full roller layout.

My guess is it is either a full roller, or some guys try to get creative and use what they call a 315 degree layout. Haven't seen it used very often, but it is supposed to smooth out the reaction. Not a very popular way to lay out a ball, but i've seen it done with abnormally short pins. Don't think that was the case though. Definitely think what you saw was a full roller with the pin to the left of the thumb (right handed). Matter of fact...Danny Wiseman used to use a 315 degree layout on some things.

Definitely unusual but what would this do with a reactive resin ball with a symmetric core if you were to do it? I'd never think of doing it but I'm just curious how one of these advanced balls would react.

315° layout Woooo that's a old one from Torgersen's old degree layout system. pretty much could only do it with a Pin-In Asym. ball. Basically supposed to give you a smooth arcing reaction, but you needed to be accurate with it.

for those who haven't seen it.

A full roller layout is not some old time layout, they use them on todays balls if your a full roller. Symmetrical and Asymmetrical resin, urethane, plastic.

The layout (plus balance hole) adjusts the players flare etc.just like layouts do for anyone else. Low flare for dry, higher flare wet.
