Hell I do limp suited and unsuited connectors and sometimes gappers in LP in the right pots and I still have the same stats that you do lol...

my steal % is 17% so only slightly higher but I'm raising suited aces and kings and sometimes other shit from the HJ on if it's folded to me...particularly if I have tightish players to act behind me.

I have no clue how to get that VPIP up other than limping shit that I dump preflop in early and mid position...and doing that means i mostly check-fold flops a lot more even than i do now...
