On the bending thing, theoretically and based on my own experiences, they are the contrary.
Theoretically, smaller hex core of the Super brights would be easier to bend than the Pro-Steels, which to my knowledge use the same (normal/larger than Super Brights') core wires as the XL Nickels (which IME are way stiffer than the Super Brights).
I'm just going on what my fingers are telling me, but on my next order - I'm going to order a set of the SB SS 45130T. Having a tapered 130T might be a game changer, and last time I ordered the SBs - there weren't any sets with a 130T. They do have a fantastic piano tone like no other, but I do like the Prosteel balanced tension sets EPS300 & 300-5 with 43-63-85T-107T-127T.
