Trig and LL,
Glad to see both of you agreeing on somthing.
Trig, the CG location is important for a driller to layout a ball to accomplish a certain reaction, basically weight hole or not, if yes weight hole, where to put it, that can be plan ahead to where to place the CG. However, there are still a lot of bowlers believe and asking the driller to drill a ball as much side weight as possible. The Brunswick video bsically is to point out there is no advantage or disadvantage to have positive or negative side weight.
LL, if you can tell the difference between 3/4 and 1/2 side weight in ball reaction, good for you, I just can't, I can't tell the difference in pin placement between 4" and 4 1/16" from PAP, I also cannot tell the diff between 1000 abralon and 1010 abralon.
Please don't jump on me, no disrespect there, just expressng what I believe.
