Cousins strap is cheap POS compared to Oris.
upd. I had Oris 65 on a ruber strap and Cousins one at the same time. Oris strap was really good, I wouldn't call it soft, especially compared to Cousins, because of Cousins strap did not had any stiffness, it was too soft and pliable. Cousins strap was a real lint magnet as are I think all silicone straps.
I will be looking at this thread with interest, because of I am too looking for a tropic style strap that would have a comparable quality to Oris.
