I actually just drilled my new g force exactly the same as my fav lrg....i would say the g force is just stronger in heavier oil. i could throw the g force out to the gutter, and the ball would recover to the pocket. i had to tweak the lrg coverstock for my house, and i may have to experiment a little with the g force.
sometimes the box finish has a wax like surface to it, and i usually use a 1000 grit pad for a couple of seconds to take this off. i did this with the tsunami and there was a huge difference.
my ball is drilled stacked 3 1/2 x 3 1/2.
the more i got behind the ball and kept the ball speed up, it hit like a train. if i backed off, or came around the ball too much, it would roll out...my release problem, not the ball!
the shot i was playing on was a house shot with carry down...will try the ball on a fresh shot monday...so far it looks like a winner, especially here on the west cost where ethey dump down alot of oil.
