Cormac - Two guys I know have had experience with Bristol and whilst they had some minor issues, they both agree it is one of the best GS available and worth the investment in time and money.
BTW - our friend Dart is the guy with the sandwich board proudly proclaiming the message - Repent now for the end is nigh. He says it could happen today or tomorrow.
I wish he would let us know because I want to go both days!!
Best of luck
