Well, at Cineleisure afternoons I stand on the 37th board and
aim for the 3rd arrow. Somehow the ball hits harder compared to
more direct lines, tell me why??? 
Yes, the most important factor in upgrading is the weight I
guess.
I would appreciate much if you can get some info for my ball,
Faball Hammer Reactive, its very diffcult to find info for it on
the net.
