I don´t think u need to open up significantly, as long as your comfortable with your game. try to close the gap between vpip and pfr a bit. keep limping, call less, raise more IP.

And please do not discuss winrates. i suppose most people here are not even close to the number of hands necessary to say anything about bb/100. This is no offense, even 50k hands might show tendencies, but no true winrate.
