A big issue with scalloping would be playing in tune.
If its simply just because "scalloped" frets feels more shiok,
all the top guitar makers would scallop their frets so all their
customers can feel shiokness.
What I meant by about playing in tune is, finger pressure.
The scalloping created a "pocket"(margin) of error, when fretting.
So when fretting a note, the pressure must be very precise.
Or you'll be playing sharp alot of the time.
I would reccommend you try out a guitar with Jumbo frets first.
Same effect to scalloped frets, but to a much lesser degree.
Jumbo frets are frets that are higher than normal.
