50NL working on fundamentals, is this spew or weak or fine?

[bellytimber]

villan hasn't had to show much down but he's LAG, 35/22/2.5, and has been ratcheting it up a lot now that table went four-handed. I want to make a stand but I guess this wasn't the time...

* I know my line seems aggressive but is it actually kinda weak?
* Sheesh, I spent 50 BBs on this. When do you think it's worthwhile raising for information?
