The hair tie thing....heard of something like that before back in the day but for the life of me I cannot remember what you are referring to. Have a pic or a detailed explaination maybe? Just curious more than anything.
As for the solo, I thought you did pretty good. I notice you don't use your pinky much....personal preference I am sure but I find that by using my pinky on long spreads my hands are quicker and in place for the deep bends....might help on the bends to give you some speed to add the vibrato?
Of course I doubt I would play it any better....easy to backseat drive. Enjoyed the video bud.
I use heavy strings, tune low, play hard and floor it. Floor it. That's technical talk.
