Smash Ace
Even after you get your techs down you'll probably screw them up in your first matches against other advanced players (I did at least) but you'll gain the ability to use them with more confidence fairly quickly. Once you've drilled enough in real matches against good players it becomes second nature faster since you don't have time to think it out to much and you'll get more comfortable. The hard part after that is getting your mind up to speed where you can think and react with that limited amount of time and not just throw out those moves that crush lvl 1s. This is where I'm at now.
