I'm thinking of buying either a Silver Streak Pearl or a Track Crunch Time for league use on synthetic lanes, medium to medium-light conditions, a typical house shot. I'm looking for more of a skid flip instead of an arc, which I already have with my Wicked BRT. I throw 13.5-14.5mph typically, 180 avg., and consider myself a tweener. Anyone have any experience with both of these balls, and what would you recommend? Drill patterns? I'm also thinking about a SS Solid for medium-heavy use, but that would come later. Thanks.
