Mountainbike Mudguards

[Kingy]

In the past I've always fitted 'Crud Guards'. Very good mudguards which work really well. But, they are big bugger and mark wherever you fit them (especially front one strapped to the frame). I've also broken a couple with comedy offs. 
Had a look around and have decided to try MuckyNutz Facefender (front) and Buttfender (rear). It's the front that caught my eye as I want to stop the spray and crap flying up at me, but would prefer to avoid fixing a guard to the frame.

I did stick the rear on when I rode with Dave on Saturday morning. Horrible conditions with gusting wind and rain. I hadn't bothered looking at the fitting instructions and hadn't fixed it inplace properly. It still stayed where it should and must have worked as my camelback (unlike the rest of me!) wasn't covered in shite! 

I'll get the, fitted properly in time for a ride this week.

Anyone else using them - or similar?
