I wish I could get down with the standard Ray neck because of all the awesome options and their availability, but try as I might it just doesn't work for me. NAMM 100th, first edition Dargie HS, BFR Redwood...in, and out in a matter of weeks! I love the Stingray. There is no badderass bass on the planet afaic. Thank goodness for the SLO. I just works for me.. in a big way. I just wish the SLO would get more design love (BFR, roasted, etc).
BTW, the Sterling neck is NOT the same as a Ray SLO neck.
I also do funky 51 and Tele builds for the fun of it, and always put J profile necks on them for the same reason and I never have a problem switching back and forth. The P neck just doesn't work either.
It seems ludicrous that 1/8" would make such a difference, but it really does...to me anyway.
And as it goes, YMMV.
