my son 21 yrs.old...lefty...bowls on the college circuit.Having trouble finding a ball that will get thru the oil and give him some room to play....There tends to be fewer lefties at his tournaments so the oil stays down most of the day....Most of the sport shots that he plays on are modified and extremely straight.Now he is a very good bowler on the house shots and has won alot of tournies as a youth bowler including a couple of state titles..He has above average revs and tosses the rock on ave,17 mph but is capable of slowing it down to 15mph.He had alot of sucess a couple of years ago whe they played mostly the texas tournaments and went to as high as 9th in the nation but is having alot of trouble adjusting to this new condition....
in short I need a ball that will give him at least 10 boards of movement....
