yeah vibratos and bends are techniques, and maybe people who like blues, like me and others on this site are not so right when they are talking about shredders being soulless players, and yeah some of the shredders do put much feeling in their playing, but the difference is that the most important thing in shredding, or at least i and lots of people think so is to show how quick you can play, while in the blues the most important thing, is to "touch the soul" of the listeners.. the ideas behind the two styles of playing are different and i think that vai wont ever be able to play page's stuff, in the right form, altough he has better skills than page... it's hard to prove your point on argue of that kind, but my point is: in the blues, there is a special feel of the guitar, which is not found in shredding, i call this feel soul in the music, and that's all
