Actually I've been wondering how the QSH Fixed tip is at wire walking tricks- El Ascensor, Staircase to Heaven, etc. Short Circuit I can but Trompo Grande I can't.
Just to add to the confusion, remember that there are 3 different tips for the QSH. C tip (early QSH if you asked for it) Gladiator tip (early QSH in Brass or steel)
New Brass (Newer QSH)
IMHO
C tip - great for regen - Not as good for wire walking
Gladiator tip - wire walks pretty fast. I like to file the sharp edge a bit.
New brass tip - the neck shape is great. The tip is not pointed enough for my fat hands, but some folk love it.
C tip with a light touch with a small chainsaw file at the neck. -
