I'm re-doing my 8'6" 4wt fly rod with new guides. I fudged some of the guide placements on the original wrapping because I was using one less guide than recommended.
This time I'm using better quality guides and the suggested number of them (one per foot of rod lenght).

The guide placement charts I have seen and my own static testing places one of the guides right on top of the ferrule. How bad of a mistake would it be to put this guide there? When I say on top I mean within 5/8" from the edge. If nothing else this would let me incorporate the ferrule wrap with the guide wrap! Wouldn't this placement reduce stress on the ferrule?
