Thimbles for 1x19 1/4'' splices

[klubko]

Hello,
many thanks. Unfortunately I am overseas (Singapore), but I can get 9/32" easily (even if I ordered e.g. from riggingonly it would be almost similar local price).
I think my problem would be that I would start to rush things, since our rig is now old and needs to be replaced at once and I wouldn't probably have a chance to test my splices.

Honestly I didn't know about Dynex Dux. I've read threads here and what I could find on the internet. I was concerned about longevity. All I found was that 3000hours of exposure to sun reduces strength by 15% and that trawlers replace their rope every 5 years.
So can I assume that it's a reliable way to do the rigging? Should I consider rope in the cover (hope for better UV protection) or just rope will do fine? I see that the main concerns are creep (seems to be less of a problems) and UV degradation. Any other?

Many thanks
Petr
