Defending the Blinds v. Bully

[anatta]

I 3-bet from the big blind against an unusually aggressive late position or button stealer with:
Any Pair, any suited paint or Ace, A9 or KJ or better. I just call with any paint not described like KT or QT. I fold everything else.

These are my default guideline, I try to alter these slightly depending on how the bully plays after the flop. If they tend to enjoy it when someone plays back at them, I tighten up.

Q1: What do you think of these standards?

From the Small blind, on the one hand, I think I should be tighter than above since the big blind can be expected to shoulder his share of the load in preventing the blinds from being run over. On the other hand, I may want to re-raise more to blow out the BB and get heads up.

Q2: Are you tighter or looser when defending SB vs. bully than in BB. What factors influence your decision?

Thanks for any help.
