I pull a burley with mine but I use the skewer mount and definately not the clamp that goes in the triangle. I will probably switch to an aluminum frame if I find one cheap mainly because if the rare hazard exists it will find me.

I have not had any issues...just be careful and well aware of your surroundings. Catch one of the trailer tires on a road sign or a post and it will very likely tear up a carbon chainstay....which is my fear.

The burley has a flexible mount and it will twist around pretty good, lessening the force on the hitch point. Again, no problems but you may want to keep a stand in the back of the trailer to keep the bike up when parked.
