Hero?

I think OTT, I could have gone fro a better sizing (pot seems reasonable) as live players call way too much with draws so I can extract tons of value. Once I'm raised here, I think it is a good spot to call and reavaluate on the river. I dont think 3betting accomplished much here as I am getting it in vs AJ/44 and flush draws only.
I am torn on this river between checking to raise or leading. I feel like this is pretty much the best river I could see as it completes the spade flush, counterfeits other two pairs and makes it very unlikely that I am against a full house other than 44, which i now beat
Leading gets value from naked 7s, Completed flushes and under fulls. I think any AQ, AK, AT, A4 is now going to be folding to a bet. I decided that checking gives me a great opportunity to get both the completed flush draw to bet and the missed flush draw to bluff.

thanks!
