Oops, thanks benny. Edited.

So you prefer something like 25/75 for a call/3bet frequency with these hands when there is a caller in between, but 3bet/fold if the action is heads up. This is my typical approach as well atm.

I was thinking of opening more hands like 10-9o from the CO; Brian Townsend calls opens like this "o EV plays". While they create more challenging postflop situations, they do have the benefit of raising your VPIP/PFR.
