In 6max, against these guys, I tend to play fewer implied odds hands (SCs, low pairs) and more top pair hands (K9s+, A7+, 88+) if they're in my blinds. Depending on the hand I usually don't mind a shove over if it's going to be heads-up. All it takes is to see them do it with A3o once, and you can call them wider. In earlier position again just fewer implied odds hands and more TP hands. Seems to work for me.
