Ah a bit cheating... we were using spinning rods and caught everything on an original perch rapala. We are super novice fly fisherman... I tend to stick to flies for trout fishing since it's more of what I know and have in my box.
Curious... in your 10 trips, did you not see fish at all? Even walking along the path I could look down in and see some legit fish (15+ inches easy) and the top water activity was pretty heavy. Just curious if the issue has been not even seeing them or more getting them interested.
