50nl Flopped Trips Line Check

[dukemagic]

So this is my first SSNL post. Just wanted to check my line here. I'm thinking I should probably check behind on the river, but what do you guys think? Thanks for the help. Let me know if there's anything I should correct/include for future strategy posts.

Edit: This was my first hand at the table, I believe, so no reads.
