rr skill, wr skill, sr skill, all of them work good, and the best of them all (zero) said himself if you REALLY wanna be good you gotta practice them all. I personally do this: sr1wr2sr3wr4sr5 f4 sr1wr2sr3wr4 etc all while I'm minoring. It works well against archers since you back up right before you hit them, and then you move forward, and that's the whole point behind sr combo. I'd personally just learn them all, they're there for a reason, you'll need them all eventually if you want to do well.
About akutee's suggestion: If you're gonna look for a good 1v1 video, look for Pato's pk video. It's ALL 1v1, and he has a simple skillbar so it's pretty easy to understand.
