I have fitted a hugger, mudsling and Puig infill panels. The first two did not make much difference to the amount of crap thrown up the back of my legs and all over the missus, the infill panel did the job, they look like they are a factory item, well worth it.
have any others tried the hugger (cheap option) not the Wunderlich one.
what make of panel did you get and what location as there appears to be a few available for differant triangles on the bike?
