I've fished Partridge a few times and generally done very well, the average size seems to 5lb's but I have had them to 12.5lb and the owner has shown me some photo's of 2 seperate 20's, it not a big water so with time you should run into the bigger ones. The water is fairly clear but the fish do come tight to the margins (within a foot!). Baits which have worked well for me are paste, 12mm pellets & prawns. Visually it's a little bland and needs some foliage around it, but the owners a really nice and it's never very busy.
