Syndicates are just another facet of angling memberships. I started one with a small group of friends on a small completely unfished section of river in Herts a few years back. The fishing was reasonable, no huge bags or huge fish but incredibly peaceful and relaxing. Well worth a bit more money at the time. I can't really disagree with them but can certainly see the circumstances when they are not favourable to some anglers.
Murray if you are serious about Red Spinners I believe you have to be proposed by a member and then accepted by everybody, they do actually use a bag with black and white balls,one black ball and you don't get in.
A friend of mine was proposed but he turned them down, he's pretty sure that he's the only person ever to have done that.
