i've fished it once and was knackered by the end of the day as it's not my usual type of venue (typically prefer low stock natural venues) i found the best tactic was to fish as far as you comfortably can, with 6 - 7 foot zigs and spod over the top, the spod mix doesn't need to be complicated i used a bag of mainlines slop/zig mix and some squashed/flaked maize which was boiled until it was really soft and soupy, mixed them both together and just kept it going in all day. On that particular day red foam was the winner however like most things i'm sure it can change.
