My cash game's nothing to brag about as my standard fare is usually SNGs or MT SNGs. However, I've noticed one big problem for me has been adjusting to a more patient style when playing cash.
While a regular in SNGs will often c-bet air, double-barrel, and just out and out bluff more as the blind rise, regulars at the cash tables tend to bluff less, imo.
And at the micros, where I play, MOST players seem to play their cards more than they play the players or position. ie, they generally have what they're representing.
Just being more patient is a big step forward for SNG players who're converting to playing cash, imo
