It depends on how you like to play, I suppose. I find the Jumbo frets a great asset to my playing and would never go back, but that's just me.
The whole feel of the RR3 is just something special, though. The neck is just perfect for metal... I never understood why people banged on about necks so much until I played my Jackson.
It was a moment, for sure.
as much as i love mine, the neck hurts my left hand these days.. its just too thin. the neck on my peavey raptor is more comfortable...shame everything else about it is toejam. needs better hardware and a setup to be any good.
