Well I was interested in rotosounds, because I got blue ones on my strat, and I loved the feeling of them and such. I got them to put on my fresh Jackson Kelly, but didn't feel too right, might have changed the guitar feel a little bit. But for me, it's a huge bonus to get an extra high E string. That's a killer deal, because we need those suckers way too often, and it's the only string that ever breaks. Overall good strings, but I'd suggest them on something like a strat, maybe a higher gauge.
