Slightly unrelated...I main Falco so I have to shffl ALOT. And I mean SHLs, pillars, and general comboing.
So here I am moving my fingers really fast with lots of precision. I got that way b/c of loads and loads of practice. And Miss Practice is a very beautiful habit to get into, my friend. Do her alot, b/c it is awesome! You won't regret it.
Also, I practice my tech skillz with Fox, just b/c he is the speediest (in general) character in Melee. I mean, he's got a fricking 2 frame lag for jump start up! Holding the jump button/direct for more than 2 frames means you full jump, so anything 2 frames or less (thats about 1/30 of a second) in a shffl.
In conclusion, if you can do advanced tech with Fox, you can do it with everyone else. One other thing; practice on level 1 CPUs, not in training mode for your c-sticking...In one player, c-stick is camera zoom, not aerial.
I forgot what else to beside this: Get better so that I may money match you!
