Villain is this hand is 28/20/15 over 1k hands. On the flop we have a SPR of 1.5. 

My question is about this spot and spots similar to this. Which straightening flops from say 678 - QJT can we shove unimproved AA on against which 3 bet / call 4 bet ranges with which stack sizes? I've listed some scenarios including flop, SPR and villians 3 bet %, we can assume we always have AA22 so we are completely unimproved apart from lets say 1 BDFD and we block none of the straight cards.

Flop 1 - 67Tr, SPR - 1.7, villains 3b - 10%

Flop 2 - JT8ss, SPR - 1, villains 3b - 10%

Flop 3 - JT9ss, SPR - 1, villains 3b - 6%

Flop 4 - QJ8ss, SPR - 1, villains 3b - 18%

If anyone has any thoughts on how we should adjust our play in these situations based on all the factors I'd really appreciate hearing it. I usually figure these spots out by feel / thinking them through in the moment but I'm sure I make a lot of mistakes and could plug some holes. Thanks!
