This thread. Look in the Slightly Improved v 2.1 post a bit down. Basically all the hands u mention are raisable, but A7s and QTs (the chart recomend folding) are pretty weak and I often fold them. One rule is to never open limp in 6max. Honestly I do, when I'm in a 'no fold or raise pf' table. Then I happily limp QTs and A7s. Sssssh, don't tell anyone.
