This is really a love/hate ball with me. I have it drilled pin above fingers, cg stacked below it (about a 2-3" pin).
The Love: This ball has a very distinctive skid/snap reaction (I keep mine polished) but surprisingly it keeps the pins low to the deck and carries exceptionally well even to this day. I've had it about a year and a half now and have put several hundred games on it. I've been fortunate in that I haven't experienced the "TEC death" others have spoken of.
The Hate: This ball *ONLY* works for me if [1] I can swing it, [2] there's a wall of oil to get it out to the breakpoint and [3] it's dry outside. In other words, the lane pretty much has to be blocked.
The bottom line, if you're bowling on a typical league shot where the lane is fairly wide open and you have a bit of swing/area then this ball kicks some major rear end! (Mostly because IMO the carry is great). However, if it's a tough, tournament-like shot where straighter is greater and break point control is critical then don't even bother with this ball.
