i average about 191 with a ball speed of 17-18 mph. i've been reading about all this new coverstock that 14lbs can carry as good as 15lbs ball.. so i said what the heck.. i'll give it a try.. but at first my driller/coach kept telling me don't do it.. well i gotta get it out of my system so he drilled me up a 14lbs total nv. i was having trouble at first.. my timing was off.. way off!! and this was like last week.. but tonight, my wednesday night league, i slow down my approach just a bit and since its a lighter ball the total nv was revving like no tomorrow. out of the gate i shot 217 and then 297 choked on my last shot never had 11 in a row and last game 225. my first 700 series. 737.. so 14lbs my sweet weight,,,,
