OLP guitar…. New Forum subscriber here…

I purchased a used, non-floyd tremolo equipped Axis style guitar. It as an impulse purchase because I liked the look. I LOVE how it plays…. and am now hooked on how the neck is so fluent in my hands. So I play new music mans and am definately going to purchase one, probably the Cutlass.
Anyway, back to the OLP. I replacing the pickups. What Non-floyd trem upgrade should I do? Do wilconsin’s tremolos fit? Is the new EBMM non floating trem a good choice? Any help on upgrades that work well with these guitars would be much appreciated!
