I’ve only fished Trelawney once which was July this year so I don’t have a lot of experience but hopefully this will help.
Down the edge is a good bet, some right munters down there. Peg wise you want 32, fish 16m to the island and you should empty the place mate. I find hard 6mm pellet works well down there but coat it in hard as nails or Gardner rig glue so it will last you all match which in turn will save you loads of time. You also don’t get as many silvers as the pellet doesn’t go so soft that they can slurp it down.
It’s also worth having a line down the middle for anything that swims, I stayed on this line for an hour, also on hard 6mm pellet. Then I went down the edge and was getting decent carp amongst the odd roach which weren’t a bad size either.
If you can fish the pole across to the far bank then this should be your main line of attack but a method/bomb can still catch you a few on the far bank.
I weighed in 40lb odd for a section win.
