I can sympathize Pinbuster. I have lost balls speed over the years down to 14's a number of years ago. I still have a long arm swing so can use my lower body to generate some ball speed but being a finesse bowler (skid, hook, roll over being a thrower) and bowling on house patterns like Easy St. 38' - 39', 18 ml 12:1 wet/dry it has become harder to score because you and I are not fluffers.
itsallaboutme has a point about changing release to cut down axis rotation.
I wish you the best PB!
