Worked a fair bit with the tutus lately and got no complaints, which is good.
Stiffens a bit but nothing too crazy, it turns into a twisty nghtmare of snakes fighting spaghetti monsters if you don't take precautionary steps and a bit of care (judging by ropes provided by some outfits) but it's fine if you do (judging by the new set i claimed for myself remaining sane for several weeks of use).
Not overtly heavy either.
On the light front, i have a 9mm Edelrid performance that i really like. Goes somewhat stiff with use but that's a good thing on a skinny rope to help avoid tangles. They do a canyoneering version which will probably replace my vintage old one when it's time to retire
