I'm still in the infancy stage with this ball, not enough info to write a full review. After a good first test on some pretty dry lanes that had a fairly flat pattern to start with, I broke it out last week during the second game of a fresh shot. And I'm a little perplexed.
First of all, I need to explain what the oil pattern looked like. Imagine around 33 feet of a standard league Christmas tree taper shot (with light oil outside 7 or so). Now imagine at the 33-foot mark, the pattern ended abruptly straight across -- except for the areas outside the 7 board, which continued to have oil on them down to around 37 or 38. Basically, a mix of THS taper with a reverse block at the end of the pattern. That's what it felt like.
This was scratch league, and three of the bowlers on this pair (not including me) have bowled regionals. One guy has shot a few TQRs before. He and one other guy shot mid-600s. The third guy (the guy bowling against me) went 225, 205 and then something like 130. And he put five or six in the ditch along the way because of the late oil outside.
Well, I went 186, 170, 158 (and won the third game). As the track area dried out, I struggled. Moving in got me into the dry too soon downlane and outside had the aforementioned oil.
I guess I shouldn't be expecting a miracle here, but I had a problem with the Chainsaw being too much in the drier parts of the lane, and offering no recovery outside. As the lanes broke down, I was eventually able to burn a spot for myself on the left lane, but on the right I had to pull a more aggressive ball out (Tsunami H20) and play in the oil somewhat. Nothing really worked on the right lane.
I guess what I was expecting more from the Chainsaw was the ability to mute the dry a little better. I wasn't expecting it to make that much of a definitive move off the spot. The biggest issue right now is that it's not as consistent as I would like.
Ball specs: 4.5-inch pin drilled about 1.25 inches straight over the ring, CG is negative side of the centerline in line from thumb to middle finger, starting top weight was about 3.5 oz. Surface is box. Works out to around a 4.5 x 5 drill.
