Mud guards

Hi,

I ripped the mud guard off my front wheel in disgust the other day - if I had had to live with that rubbing sound for another second I'd have gone mad.

However, today's damp ride into work brought home to me that I will need a new set pretty soon.

I'm not sure what I've got on my bike at the moment, but they're shite. Can anyone recommend a set for me, please? My bike is a Specialized Tricross.

Thanks.
