Almost everyone I know who has ridden Profiles has been through at least one pair. It's almost like a rite of passage.
I'm not fat but I am pretty tall. Back then there wasn't any decent alternative - I had a set of Prince Alberts once and they lasted about two weeks - whereas the Profiles would last a few months at least. I did return a couple of sets, including one arm in particular that bent (!).
Primo Hollowbite all the way these days.
