I play 6100-sized fretwire on all my guitars, so I appreciate and am used to the feel of tall frets. The control you have is second to none, and of course the ease of playing is welcome. Properly set up, you can fly on fretboards so equipped. But, a full scallop just takes it a bit too far for me. While tall frets tend to get the fretboard more or less out of your way, you can still feel it. The total loss of any indication that a fretboard exists that scalloping brings is a bridge too far. I suspect someone came up with that idea before the very large wire that's available today existed.
