It depends on how much booze ya got in ya, I guess!!??? LOL!!!
Seriously, though, as we sit in our bedrooms and noodle,,,things come so easily,,,but up on stage, lights blaring, people staring, things get a bit more tense (thus the booze,,,or heroin, or crack, or a quickie before the show from some gutter slut---whatever the kiddies are doing, nowadays), SO, I would play it safe: Less in more! Feel your way around the Vamp, at first, and pick your spots...then FLOOR IT.
See? One thing about Ursin, he can accelerate like a Ferrari!
(Whammy tricks & other effects work good in this situation, too)
