Which RB XL are they and why did you get so enraged? I'd heard bridge clearance isn't good with them...? Also quite interested in how you find the RB Long mk2's (as I've been a long time RB L mk1 convert).
Thorns everywhere around here too - the majority of farmers use a contractor to cut roadside hedges that the councils don't do - some of these guys are brilliant (the ones given the council tenders usually) and others are just a local farmer who owns a hedge trimmer!
I don't know, the crap version you mentioned, I think... with the rubber flap bit that slots over the end. I think they gave decent coverage, but I probably didn't set them up properly - I did NOT use the screws to firmly attach the clips to the guard bit, so whilst riding they slipped down going over tiny bumps, presumably and were soon rubbing the tyres. By the end of my 8 and a bit mile ride they immediately stopped the front wheel as soon as you let go of setting it spinning. I did wonder why it seemed to be getting harder on that ride
They didn't provide great coverage at all, since they only went up to the back-facing side of the rear caliper, or the back of the forks (rear/front guards, respectively)... I want something that has almost as good coverage as the RR2, so it directs water back down at the road, rather than all over my legs... but without the utter cackness of them rubbing/falling apart/moving. Hopefully these will be just the ticket - quick release too, allegedly. I will fit them tonight on my super-clean again bike.
They seem to get mixed reviews on Evans/Wiggle, so we shall see. But you've said SKS have been great customer service wise, so I shall shout at them if I have problems. Or just buy a proper winter bike and cry.
I do actually hate getting filthy on rides, apparently. Needlessly, anyway.
The XLs were quite stiff, the plastic bit - so that didn't move much... I haven't had a fondle of these new long ones; apparently they are flimsy - we shall see. If all else fails I'll just fit the XLs properly and deal with whatever shortfalls they have. Some coverage is better than none, i guess.
