i have had 2 power grooves both teal purple,1st one was stollen, and the second one I bid on last year and forgot to pay for. this one i had drilled by one of your friends ,dont know his name on here ,but man do i love this ball . price after shipping and drilling is about 70 bucks . I am pretty sure this ball is gonna make that and some this year. I have had some balls that i thought i was crazy about ,but this thing , man. Maybe because i am such a bad bowler i needed to throw low end stuff ,but what ever the case,this polished power groove has all the back end you will ever need on a med to light shot. the carry with these balls is phenomenal. they come sanded my driller hit it with 1200 grit and then polished it . If you ever see one on ebay ,they are always there for 10 bucks, its a great investment. when this thing finds dry its comin in hard,if you miss left it will sit down in the oil and just when u think its a wash, 10 in the pit. I can play it up the boards and it will skate for 50' and then come roaring back if there is oil and when the lanes break down it opens em up like a can opener. And its so predictable even in my hack hand.I picked up a passion for 80 bucks drilled and it really isnt much stronger than the groove,its a good ball dont get me wrong but i play maybe 2 boards right with the groove ,(its polished). I think you would be hard pressed to find a ball this good Imho for the money.
