"No Civilian Club can do the number of launches per day that a VGS does and still meet the requirements of the members (who pay a fair rate for the privilege)."
Really? Have you looked into how many launches per day a well-oiled setup with 1 more instructor than glider and plenty of helpers who know what they are doing can achieve, even if it's a 2-wire winch?
Granted you would need to look at the larger clubs, but there are a number of clubs that can provide a very impressive service. Even if it's not what the VGC did provide it's infinitely better than what they can currently provide... Also, most BGA clubs do air experience flying, generally about 20 minutes flying, and are generally happy to do something out of the norm if asked to do so.
