I recently have gone from a Twin to a IL4 and all i can say is, although the SV was great fun and a brilliant bike to learn on I don't think i could ever get back on a Twin unless it was something like a TLR/Mille or a SP1/2, something with MASSIVE power!
All in all, personally i think IL4's are the way to go, not only for the top-end power but for the smoothness too.
Do it, go out today and buy one
