I'm totally generalizing, but I'd say both. The old Opto plastic seemed to be much more resistant to cuts and nicks on the rim, while still retaining that supple feel. Now it seems to be much less durable, gaining noticeable wear much more quickly and the plastic seems a little more cheap feeling. Slick, stiff, and not as gummy.Loss of durability. grip...?
TBH, today's JL reminds me a lot of old Opto. :\
