I moved down to Somerset from Shropshire, and the meres, back in early 2000's. I'm now back up here.
I was a member of South Cerney and it has a lake on there that I wish I could have spent more time on. Massive and, for the best part, an unknown stock. Very similar to Bradleys before they lost it off the ticket and it got stocked with thousands of stock.
Huntstrete is a nice lake to spend time on. Check out Useph's posts in the blog section.
You could even venture down to Bridgwater and join the local club. They have a lake at coombwich that might suit you. If it were me though, I would get a ticket for Horseshoe and get my name down on Farriers.
