Personally i call the raise (it is only a min raise after all) and see what the flop looks like, if its all rags i'll bet out on the flop and hope to take it down, if i get reraised i think i'm up against a high pocket and look at my odds. If i get called i might check the turn and see what he does.
Why are you playing 25NL these days? I thought 3/6 was your scene
