V is a aggro fish. Keep cr a merged weak range otf, suck as tpwk

Hero has K7ss
Hero on SB raise to 12.5, V calls

Flop 2d6s8c
V check, Hero bets 9, V cr to 30, hero calls

turn 5s pot 85
V bets 50, hero raise to 180, V calls

River 3h pot 435

Hero has 900 behind.

My thoughts:
Playing this deep, I think I have all 34, 47, and obviously 79, which are 44 combos.
We bluff raise turn 27ss, 37s, T7ss - A7ss.
We may also bluff raise turn 29ss, 39ss, T9ss - A9ss. That's total 14 combos, then we can also have another 49ss as value.

We have 45 combos and 14 bluffs

Given the fact that V's range uncapped, as he can still have 79, we should bet a smaller size based on our 3:1 value: bluff ratio instead of a large one to polarize our range. Then we are probably bet/fold all lowest straight, and bet/call 47 and 79?

Does this sounds a solid strategy?
or should we add more bluffs and choose a larger size? Or we might call some value combos ott so we have smaller number of value combos otr?
