The Niagara River you say? You're in my neck of the woods. Go light. Give a 150 Leopard a try. It was the first disc I was able to control with any sort of reasonable distance and 5+ years later I still have a 150 Leopard in my bag. Of course with the constant breeze coming off the river at Beaver Island SP, you might want something a little heavier and a little more stable like a Gazelle. Don't be afraid to throw light plastic into most a breeze even when its in your face, but a strong headwind can cause problems with a light disc. Your Buzzz & Eagle should handle the stronger headwinds.
Maybe I'll see you out on the course. My home course is Joseph Davis and its a great course for learning the game. But the wife and I play all over WNY. And don't dismiss Veteran's Park in Tonawanda either. Nothing over 200' and only 9 holes, but its a great place to hone your upshots and putting.
