I really think KJo is almost a "must play for a limp" in MP or LP. The great thing about it vs. 65 is that it hits very often. TP is also usually good.
I also think 65o is playable only under exceptional circumstances. VPIP of 14% isn't insanely tight imo, although you can play a little more.
Basically, I think all of these decent TP-type hands are for keeping up with the blinds. You really want to just take it down on the flop when you hit, but you'll also get some station-ish players on draws that usually miss and will pay you off through the turn, too. You just have to be able to bet it healthily and lay it down when you're beat...
