Is urethane a crutch

I recently got into two handed, and I realize my one handed ball that I was using which is a hammer effect is unfortunately too strong of a hook, and I have to play completely left of lane which I’m not a huge fan of so I was looking into other options that are weaker for getting into it And the pro shop operator told me my best bet would be a black pearl urethane but I know some people say it’s a crutch but what would give me the same smooth reaction with a lower hook
