Glencorse is a beautiful water, quite big though and fish can be hard to find! but thats fishing, fishes well with traditional flies and the kate mclaren is a personal favourite, behind the island and down the road shore are always worth a try and if the wind allows it a drift close in down the far bank can be superb fishing.
What are you going to be stocking it with ? hopefully you wont go down the big fish route! some cracking fish in the water and the natural brownies are crackers, it does get poached along the road shore though by polish guys so worth keeping an eye on that!
Any bank fishing going to be offered ? dont think the banks been offered before but there are a few bits that would be good.
Anyway, good luck with it and i will defo be up to fish it next year
