Ran a set of twin sheets. Heavy Duty cycle, medium soil level. Absolutely no tangling. Even the two pillow cases were *not* caught-up in the fitted sheet. Could be a fluke, dunno yet ... and could be a different scenario on larger sheets.
The softener dispenser seems to do better if the softener is mixed with water first in a cup for proper dilution, and enough water is used to fill the dispenser to the max-line. I used the lavender Snuggle again on the sheets, and the dispenser was clear.
Larger loads tumble better, of course. Ran a small load of cleaning rags/towels, and rollover was much less pronounced, although sometimes the tumblers caught the items in the right way to give them some good flippage. Used Super Wash with Soak & Stain Treat soil level, hot water, liquid Gain HE (finished out the bottle). Cleaning results, *very* good.
