The A7 is fine...ppl will show up with random stuff enough that with odds it's a call. KJ is close...really not sure what's best. J10 is just gross, I think your shove is fine since so much missed. I'd obviously fold 99 on flop there if i'm going to flat the 4-bet oop, but i'd almost always just shove here until we're more than 150BB deep.
