In reply to SeanT:
Thanks all for the input.
Made my decision based on the UKC massive.
Ended up getting some £15 Cebe ones from TKMax as recommended above, reduced from 70 with hard case etc. The lens are ok (cat4), but they are not in the same league as the Oakleys I was going to buy (£125 polarised ones) for clarity, so we shall see. They seem quite solid, but look a bit silly, really big lenses so make me look like a fly. Dont really care tho, I'll be hanging off a cliff in them.
If these are not upto scratch after some use, I shall be taking the plunge for the Oakleys as the lenses are really much better then anything else I tried. Also, the CEBEs dont have as much rubber on the arms. I am going to perform a DIY job, which may just ruin them.
All in all, really good value for money at £15. Maybe slightly clearer lenses than the Blur ones and simlar build quality. The fit on the Blue ones was better for me tho. We'll see if they survive a trip to kalymnos, that will be the acid test.
