Well, I'd have to see which technique you're talking about. I also play R.O.B, so chances are I already know about it. I'd caution against putting all of your stake in one technique, though. After all, if someone circumvents it in a way that you didn't expect, you'd be left high and dry.
It's why I 'm a terrible Snake player.
I also wouldn't count on edge guarding Yoshi. As you saw, it is much, much, MUCH harder than most people would like it to be.
I'd be down for counterpicks next time we play. Except for Delfino, we never really played on them, so I can see your point.
You've got nothing but respect from me, man. You've got the guts to stick with a character, and the brains to know what he is and isn't capable of. We're two peas in a pod when it comes to that. Let's do our part to keep representing.
