I suggest fold to 3bets more. Calling a 3bet 50% of the time is just pure spew. My own fold to 3bet stat is 70% for 10nl (I play FR tho :/). But still, you need to start 4betting or folding to those. Calling just sucks, especially if you are OOP. You give away all initiative. You are pretty much forced to check/fold when you miss, and thats just teh gay lol.
