If you're standing next to them, you can react in time and get the grab. I do it, and I've seen lots of others do it. Just look at good Sheiks.I don't agree that "react faster" is legit advice for grabbing tech in place shine.
What I said was:If one could simply "react faster" and do that then you wouldn't even need to chain grab or use uthrow combos, you would just tech chase them forever without having to make any predictions
I never said you should "rely" on it (sometimes it's worth going for, sometimes not. Depends on positioning, mental state etc.) or that I expect Marths to "perfect tech chase" (you don't even need to tech chase anymore after getting the grab. Just upthrow or throw them off stage).
I've never said that you should react to the tech in place regardless of the situation (as I've already said, sometimes it's good and sometimes not), or that you should keep going for tech chases after getting the grab. At the risk of sounding like a wannabe-debater, please stop straw manning.
To be completely clear, I'm mainly advocating reaction --> grab when you stand right next to the spacie as they tech in place. It's obviously much less plausible if they're a bit further away.
