I am bowling on a 43 foot sport pattern with some heavier oil currently. so far my best looks have been my Axiom and Nuclear Cell.
the Axiom is not giving me a lot of angle honestly it is playing closer to a IQ tour in terms of shape. it is still more backend down lane, but sharp angle it is not.
the nuclear cell I have left at the out of box shine for now; and when it hits the break point, it goes. I drilled it so that it wasn't so "hockey stick" motion. but it still glides down lane and turns hard; its just a bit sooner. since you are struggling with sanded (all be it, older and well used) stuff, perhaps a nuclear cell at 2000 or 3000 sanded would work.
the new physix is interesting, but it is still a few weeks from release. very interested in how that cover and core match up.
if you need something closer to the sure lock in terms of "strength" the Roto UFO would be the ball that is already out from storm/roto to look at.
had a guy pushing 80 in my sport league last year, and that UFO made him look good.
