HI PMG - as far as i'm concerned the RAB strings are as good if not better than anything else out there and usually once I get my customers to try - they love them. For the price I pay, you can't go wrong either!
I've not tried the EnduraEdge - i'll have a chat with Adam or Richard next time I place an order and get a set to try.
