hi mark,i bought one of your crud catchers and was really pleased with it,top bit of kit,
the heel guard,well the standard one does its job well on my bike,
but mark,you seem like a robust character and you did ask,the side panel infils imo are not good,i wanted to like them but i cant,should have gone over frame tubes to offer more protection and to allow p clips to be hidden underneath,so you just see the fastner head,soory to criticise i could not do anything like this and i aplaud you for what you have done,but you did ask,
a stainless extender below number plate,a bit wider and longer than the wunderlich one for ex would be a good next project for you i reckon

It might be an idea to post up designs first before going into production to get some feedback. These are constructive comments only.
