Wow Akira dude, I love the shape of the Fly Mojo...played a gorgeous one once...but alas it was not to be...bit too much cash.

as for the nicest shred guitar,I'm gonna go with most people here and say "whatever feels and plays bets to you". My personal favourites include the Parker Fly Mojo, and Ibanez Rgt2020 (which is kinda like an Rg, but gorgeous mahogany (or Ash) wings, on a purple heart and walnut (I think) thru-neck...really toneful, fast guitar...I find the standard basswood Rg's toneless, and the same with the Jems)
