You should really put something about what the thread is about instead of just "Hi guys".
Because you know I'm going to suggest you don't try finger roll Gengar.
I've roped with you many many times and I can tell you now that it will be a total disaster. This isn't meant to be insulting to you but I like you mate and I guarantee you will end up getting really frustrated and it will majorly slow you down!
You could try finger rolling for 10 years but without the basics of roping covered you will get nowhere seriously.
It's like a wizard trying to learn the most complicated spell, but until he's learned to hold the magic wand properly there is no point in trying.
Instead of smashing space loads of times, just a little Up + Forward diagonal arrow press followed by a single space can give you a burst of speed.
Pressing the space bar immediately after the rope connects to the wall takes precision and timing but this will give you fast repeats. It's nothing to do with tapping speed although that will come when you get used to the timing.
Mate to mate, I'll only say this once (maybe)
"Please don't try finger roll!!!"
