I dig the Chappy's the most of the ones listed. The Cali is a sleek machine, but despite having owned several I have never kept one for more that a couple months. It was always a tone thing and when faced with the prospect of swapping pickups I always just punted A Diablo is cool, but the lack of any single-coil options (stock anyway) made it a bit limited for me. Away they went. A Chappy does it all for me, and I wish I had my old Sustainiac porch-plinker back sometimes, but in the end I think I have an issue with the sound of a Floyd-equipped mahogany=bodied axe? I think Alder is the way to go for a true "shredder", but that is just my opinion. That said, my fave Hamer is my SS Custom, in all its "hog and Floyd glory, but it is a much warmer, fatter sounding affair overall. Maybe it's the shorter scale length or they just added extra "mojo" that day in the old shop.
Don't overlook the Centaura, as they seem to get the least respect and can be had for a reasonable price usually. In my opinion, the best "Super-Strat" in the Hamer lineup is still the SS though
