All I can say is I've owned one of Kenny Fulgham's rests since he first started making them back in 2000 and am still as big a fan of it now as I was then. Arguably, the only way you could have anything more would be to go with a one-piece, and that's not necessarily so.
I did add one of Fudd's tops to mine as well as "upgrading" the windage adjustment screw and 3 leg screws from 3/8" Coarse Thread to 1/2" Fine Thread, but that was only out of personal preference.
Good luck.
