setup question

Hey all, I just picked up a Stingray to keep my Cutlass company. I can’t get it to play as easy as the Cutlass, though. There’s something about the Cutlass neck that just seems effortless, a sweet spot at every fret — but the Stingray feels like I’m fighting it, having to use a lot more force to hit the note cleanly, and I have to get the strings higher for the note to sound right. Both are running Super Slinkys with the trem decked and 5 springs. Neither one of them seems to have any relief in the neck but the Cutlass plays beautifully without it. Thoughts?
