im looking at drilling a jazz i think this week just wondering what kind of layout i should put on it. i was thinking maybe a label. sorry i dont know much about layouts, just the very basics. my pap is 5 7/8" even. i have a scout and blue vibe that i would like to fit the jazz inbetween. the scout is drilled at 90* so pin under ring with CG in. the blue vibe is 135* i think. its the #4 drilling for high trackers on hammers site.

my specs: lefty, high rev player about 450-475 rpms. 15.7mph ball speed.

i have been having trouble late in tournament where my blue vibe is just too early and my scout still doesnt have a good reaction and carries. i think i am going to dull the scout a little but i think the jazz is the overall answer.

sorry for the long post and thanks in advance for everything

p.s. go leftys

Dont have as many rev's as you(375 or so) an I drilled one 51/2'x 4 with pin under my middle finger.The ball goes looong with a good turn off the spot.Its my weakest ball under my Liberator.Plays real well off the 3-4 board on any house shot or short oil.It also worked well on the cheetha pattern this summer at 3-4 at the brek point,playing straight up the lane.I have two others to drill when that one dyes.A very overlooked ball
