I suck so much at playing guitar that only DT solos I can play are the ones on Learning To Live, Goodnight Kiss and About To Crash :E
I am left-handed but I decided to start play guitar from the right side. So, my left hand is "fast as shit" but my right hand sucks with the pick.
I suck and I hate myself for that.
But yeah, I forgot to answer to the actual topic question, Hardest solo I've ever tried is the final unison solo on Take The Time.
