Two of the teles I've built (1 PBG, 1 non) have front and back comfort contours (ala strat). I think it makes a great guitar design even greater!

...I don't trust enough in my abilities to take off large chunks of timber and not make it look like I've taken off large chunks of timber.
I've said this numerous time here but, I have done my contouring with a 4" angle grinder and a 80 grit flap disc.
Not for the faint of heart though! At 10,000 RMP, it makes short work of any timber!
