Sorry, I hit edit on yours, instead of quoting.

Here was my response.
If you actually hit them with 6A, you would get them to clap with other moves. (one example being j.b > allegretto.) The problem with j.A spam, is you're not going to be able to combo off of it, even if it hits clap. the proration will have gone to shit. j.A spam on block is totally viable though, as it can lead to unblockable set ups.
Tech traps seem too hard/risky with Carl.
It might be plausible, but I wouldn't really plan on going for it, as strat. Only if it looked like I could. Kind of gimmicky.
