This has been discussed at Brighton on a few occasions. I tend to agree with a circuit idea. Though am very wary about tea bagging in the flat water area section behind the groyne. As this lines up with the carpark track, and seems to attract plenty of swimmers and kids in this section uptil about 20 or so knots. By encouraging many people performing their tricks behind the groin, also promotes the show ponies, and could cause problems, I actually prefer people doing their tricks further down the beach as their are generally fewer beach goers.
All else aside, a circuit is needed, and I have been following this mantra pretty much for the last few years.
