One thing that helped my transition a lot was treating table/game selection as its own skill. In tournaments you're stuck with whatever table you're assigned, but in cash you can actually choose to sit with weaker lineups or leave a tough table without any penalty. That single habit probably improved my winrate more than any range adjustment. Also agree with the point on early position - I tightened up there specifically because limpers and cold-callers in cash games tend to be stickier post-flop than tournament players who are more willing to fold to pressure with a shallower stack.
