Preface: I play .50/1 NL and 1/2 NL at Full Tilt.

This play has been bothering me lately. It just seems stupid from the button and cutoff. Basically, I limp in with the same hands I would in middle position, broadways KJ and lower and ATo, AT-2s, 66-22 and sometimes Kxs. (Side note: I do not know anyone who plays KJ as weak as myself).

So is this play really dumb or should I perhaps do it more to balance the fact that my attempt to steal blinds percentage is 45?
