Nicholas,
Sorry for the tardy response - work commitments!
Yes its a stunning piece of water and I was really priveleged to share a rod there with a friend - we had a day each weekend - each! and it wasn't silly money either. Then the estate put the fishing in the hands of agents who banged the prices up and I couldn't justify the cost anymore. Also the membership changed from a few really nice local retired people (who preferred to fish during the week - result) and the place became overrun by unfriendly city types in chelsea-tractors with poor skill levels and even less etiquette.
The keeper used to let the local club (not sure which one) have some coarse days after the trout season - but some anglers abused the privelege and he stopped doing it. I know that as a paying rod I could have had the odd day but I never had the time. When I fished there, the keeper (top coarse angler himself) ran it very much as a mixed fishery - coarse fish were not definitely not nuisance fish then, and there were some mouthwatering specimens. I personally had roach to over 2 on the fly and the chub were like like donkeys!
If anyone wants to contact the keeper, please PM me and I'll find the contact details - but I think a rod is over £1200 now.

PS having suffered a barbed longshank 6 black lure in my earlobe once - I would definitely say that there are other benefits to barbless! Cut the leader and bled like a stuck pig until I'd finished obviously! But I would always use barbed for fish I intended to kill and eat, and barbless at all other times.
