Lmfao! I meant to start this very same comparative discussion yesterday, but my hard drive died before I got a chance to! Anyway, the black & silver spartacus clamps seem nearly identical other than color. The reviews I read made it sound like they may stay on a bit better and have more of a bite, but definitely, neither are for beginner's. These are a tad bit more advanced than the ones I have now, will be my 3rd? 4th? pair of clamps in general, so I'm fairly certain I can handle any of the three but if you're not looking for as strong as a bite, I'd go with the fresh jaws ones (though they sound pretty wicked evil too). As for me, I think I'm going to go with the black ones (Butterfly) from Spartacus. Among other things, the pics make the padding on them look best to me as well. Whatever you choose, we'll have to compare notes!
