I feel that I have a pretty good release already so changing my release probably isn't an issue . I bowl on synthetic overlays , and I'm looking for something that's going to give a little pop on the back end , because my defiant soul after a game or game and a half , rolls out just a bit . moving doesn't seem to help this problem .that's why I was thinking sanded pearl vs sanded hybrid . if you've ever bowled on overlays , you know once the area is gone its just gone no matter where you move .
I don't think anyone was meaning for you to "retool" your game, but just a subtle hand position change will alter the shape of your bowling ball through the back part of the lane. As far as the overlay is concerned, are you talking about Guardian, which is very soft, and only breaks down, which would have your bowling ball over hooking, and not slowing down and turning the corner weak; or are you talking about synthetic panels like HPL, DBA, Pro-Anvilane, etc.., being placed over the existing wood lanes, in which case, is %95 of bowling lanes in America that have converted to synthetic, as it isn't near as cost effective to completely rip out the wood, and start fresh? If it is the later, then what happens is, the synthetic lanes takes to the "shape" of the the wood, and what ever topography you had with the wood, is then seen through onto the synthetic. In any event, unless the lanes are AMF HPL, they are often crowned and lead to the ball wanting to push right, as the night goes on, and the pattern becomes "longer" due to the oil moving downlane. A simple bump right would get you back into the pocket, and eliminate the weak ten or seven pin hits. I know a lot of people talk about "burning up", but I just don't think that happens as often as general consensus says it does. Storm did a video about ball surface with the use of Earl, the machine that the USBC uses to test equipment. They put fresh surface on a Nano, and threw it at 4000, 2000, 1000, 500, and 360. Every shot hooked more and more, which contradicts a ball "burning" up(Surface is your freind as long as you can still get the ball through the front of the lane to the midlane). Chances are, you may have just enough surface on the ball to get off the spot when the pattern is fresh, and backends clean, but not enough surface for the ball to continue through the carrydown as the night progresses and as oil starts clogging the pores of your bowling ball. Either way, a simple bump right would help. Often times switching to a weaker ball to "save energy" only allows the ball to skid further outside at the break-point, and hit drier boards, thus giving the illusion that the ball has "saved energy", when in fact what has happened, is you are now going around the pattern that has carried down, and with enough games bowled, provided the fronts hold up, the same thing will eventually happen.
If you are talking about the lane just breaking down, and the ball won't skid to the same spot, then maybe look at a Marvel Pearl, or try a Totally Defiant, as it is the pearl to the Defiant Soul.
Hope some of this info helps.
