@gelaundry4ever Yes, Logixx posted the link to the manual.
There are plenty of options / programmes, of which all are listed in the manual, and also shown in my video overview above!
The AntiStain allows a selection of 16 stains, all of which change the wash cycle accordingly (more intensive wash, more heat, or heat maintaining and add a soak etc).
There are features to add upto 3 extra rinses, extra water (although on some programmes the difference in extra water is only little!), silent washing, Rinsholding, short wash (speedPerfect), IntensivePlus (extended wash time), pre-wash etc.
The options are so flexible its really great !
As for the Towels wash, as long as towels are dry before loading - I have filled it upto 4KG (according to the loading bar on the display which appears when the door is open): 4 Large Bath Sheets (Quality Egyptian cotton ones), 3 Hand Towels, 5 Tea Towels, 4 Flannels and 2 standard size bath towels. Generally towels get very heavy when wet, so I'd imagine that's the case of not being able to load more to that cycle. The Towels cycle also uses a rather long final spin with fluffing technique so I guess Bosch want to ensure there's enough space in the drum to do this effectively!
I decided to use Rinse Hold when washing Towels, I then select the separate 1600 spin when I'm in a hurry to finish towels, as the separate final spin holds at 1600 for 5 minutes, yet takes half the time of the towels final spin sequence! (always great when you find little tricks hidden within the machine!).
Thanks Jon for your nice comment! Your Siemens is a great machine too - very similar indeed! I'm still experimenting with different cycles! But I'm with you in the Cottons Speed wash, and Mixed load cycles are very good! Also quite liking Mixed Load with IntensivePlus option (Which I think now is more like your PowerSpeed 59' programme but with Intermediate spins). Was also quite impressed with the 30 minute wash (For refreshing)! Plenty of jet action (a much better cycle than my old Hotpoints short 30 minute wash)!
