I can only offer anecdotal advice .. but I have used a Parlee one on a hybrid red (Dura Ace, Tiso front mech and know Red) mechanical group for getting on three years with out issue. Unless there is a defect in the layup I'd suggest it will be fine.
The Exotic is indentical in apperance only. I am not 100% sure on the manufacturing method, but the one I had appeared to be a glass fibre radius pultrusion with a carbon beauty layer.
