When I was up there a couple of years ago dependant on colour and weather you would start at 6m (13 if cold and clear) while feeding a 3m line and the margins.
It was very easy to get too many fish in your peg and foul hooking (and subsequently taking too long to get fish in) certainly cost me a couple of pick ups.
If you do get too many in your peg hair rigged meat on the lead is a good tactic on the same line and just wait for the baitrunner to start spinning! lol
Last hour for the margin but drop in whenever you see them.
Some of the venue regulars fish fairly light 0.11!
