Preflop play: Good quality play, I like you logic and sizing. Could go bigger, but not an absolute must and I don't see it as an error
Flop Play: I do not like this sizing as a C-Bet lead. I'd probably go $100-$125 OR check with the intentions of check-Jamming any bet by your opponents. Check jamming would maximize fold equity, while betting larger will build the pot when you hit and should probably get folds from hands that are set mining. Betting 40ish percent pot lots of hands will stick around that may get sticky on later streets. $70 bet, I'm calling with TT/JJ in position on this board with only 1 over and some Gutshot backdoor draws, where as I am more likely to fold these hands if I am one of the two players in later position facing a $100-$125 bet.
V1 can have all the sets, v2 can have bottom and middle sets on this board. other than sets, both players should be capped at 1 pair hands
KTss/K9ss is a possible hand you could be up against as well from either player.
