I was wondering if there is any merit to the idea of putting spinning rod guides on a fly rod. I saw some pictures of what I believe was a fly rod made by Great Bay rods and it looks like they have spinning rod guides on them; furthermore I read a comment by a fly fisherman saying he could cast 90 ft with a rod made by that company whereas he couldn't get past 70 feet with is Z-Axis rod. In addition I have an Orvis Helios 8 wt that has much larger stripping guides than any of my other rods and I can cast further, easier with it.
So I'd like to know what would happen to my fly rod if I put spinning rod guides on it. Would I be able to cast further only to see accuracy go to pot or would I make it so heavy it would wear me out or would some other bad things happen?
