Starting to play 6-max vice FR

[Bruce D]

I have logged about 5k hands now at 6 max, 3k of them recently and I now have a better grasp and feel more comfortable at 6 max than I had in the past.

My table selection and, as a result my seat selection has been outstanding, getting seated at table where the average vpip is over 50% and many times lucky to sit on the left of a 70+ vpiper.

This is obviously a huge bonus.

I have been trying to isolate the bad player with marginal holdings, ie 77+, A8o+, KTs+, A7s+. However, with most of these games, the players behind cold call soooo much and leaves me little information when they peel a flop with any two cards. It pretty much makes for a c/f with nothing out of position on the turn or river.

With this in mind is it best to go back to calling with these hands (minus the A8o, A9o)and then punish as per normal with the premium holdings?
