Fly rugs that don't rub?

I have 4 rambo ones, the green flyfree ones and 2 protectors, they are really good, the protectors especially.

Ceryn has been wearing hers 24/7 since about march and has no rubs, the others have had theirs on 24/7 for a month or so and no rubs so far, I have 2 Tb girls with very high withers as well. :)
 
Best i have found is the derby house fly rug for not rubbing

This year i bought both my lads the mark todd ultra as had great success with other mark todd rugs. I am dissapointed though - not good fit on either and would rub if left
 
My boy wears the sweet itch hoody 24/7 & he has quite high whithers, it rubs him rotten :( He has a big white mark (which I thought was the saddle originally!) but its where the rug is rubbing him, he needs it to stop him itching though.
