I've always had a decent days fishing at Innis. Even to the point of fishing 'till it's so dark I couldn't see the end of my rod and not been shooed off.
What problems have you had with the place?
As your name is Marazion Midge have you ever tried Tree Meadow or even The Drift. Now that is a beautiful place to fish (even better if you're a float tuber).
I've got no connection with any of the places but I do come down to work in Cornwall for 3 weeks every year so it's always good to mix work with the important things in life.
