Fenders and front suspension don't go well together

The best fenders for keeping water off you are the full-length ones and are just about impossible to fit with a suspension fork. I've found any fender that is mounted on the fork brace either doesn't provide enough clearance off-road or hits the wheel when the suspension compresses. I'm now using one that mounts in the underneath of the steerer tube and it's a lot better.
Mine's a Filthy Muck Sucker but you can probably get better made (lighter) ones from other manufacturers.
