This has truly been on of the most interestingly intriguing threads I have ever read. It really does show how all front loaders despite having the same appearance in design, behave differently from one another causing issues here and there.
Judging that load I really can't see anything wrong with it. That size load is what I put my in my WP Duet WFW72, 70-80% of the time and never experience issues. I've heard people from time to time throw around a rule saying not to wash towels with clothes...well if I see a stray towel or two hanging around, and theres space in the washer still, I end up putting them in, turning the machine on and walking away. Results are excellent with no pilling or anything, I've done this with my old Tl'er as well and experienced the same thing. We have always used tide powder in both machines and never experienced uncleaned clothes.
Another thing with what I've noticed with my old TL and FL, is that lint in the dryer on the screen with my FL, has decreased dramatically to the point I often don't even bother to clean the screen out load after load. In my old TL, you could expect to clean it after each load. So that there tells me gentler performance.
At this point, all I can think of is all that dry tumbling during the sensing phase and the stupid pulsating fill. Here's a mini experiment of what you can do sitting right at your desk, take your shirt that your wearing and rub to sections of it together gently, this mimics the early sensing and pulsating dry fill phase of what the LG FL does, I myself can feel and tell how this could easily cause pilling overtime of laundry.
Pilling occurs when the individual fibers in fabrics which are tightly held together, begin to come lose and that's when you begin to see fibers sticking up making rough spots, of course the cause for this is...you guessed it clothes rubbing together, but mostly when dry.
But back to LG's sensing and filling. LG FL's without turbowash probably experience the most pilling which would explain the gardenweb thread as due to the pulsating fill on turbowash- models, clothes are being tumbled for much longer dry including the sensing phase. On the turbowash+ models (yours) clothes probably still face too much dry time as when water most likley enters the tub through the jets, the clothes are just partially saturated leaving some dry spots, and the weight of the wet clothes rubbing up against the dry parts of some fabrics can cause pilling in turbowash models too. Even the spin distributes do some really elaborate moves which further add to pilling.
BUT, here's to another possible pointer. LG recently updated all of its FL model baffles to a more updated, curvy design similar to SQ FL's as opposed to the old chunky square, short but tall baffles. Could the baffle changes some how could've helped or remove gentleness?
