just got mine punched up drilled it 30x4 3/4x50 val hole up,this is a must have ball for med to heavier oil,it is so smooth,reads the mid-lane very good and then makes a very smooth path to the pocket and continues right thru the pin deck, i played it from 12 to 8 and it just reads the mids great and has plenty of energy when it hits, moved out and swung it from 20 to about 12 and it really keeps the nice move to the pocket miss right and it will climb the hill and make it all the way back carries the light hits very well if you tug it alittle it holds the line best it can and destroys the pocket. very good ball. seismic makes great equipment time to notice the outstanding job these guys do! thanks again
