I said that.
I did lots of rewraps years ago when I worked for a famous rod builder in my area. In the old days they used varnish and Polyurethane on most custom rods. The Varnish and Poly cracked from stress over time and water got in there and then the guide would start to move. Now a days with Epoxy, that doesn't happen as often because the Epoxy is gummy and there is give in it. You can stick your fingernail into it and watch it come back. Try an remove a guide today. Its not easy. The rod will flex and the guide will flex also under stress. , but the wrap doesn't. The Epoxy seals really good if done right. The guides are build better today and the welds don't brake easy unless you step on them. The rings will come out and split if abused also. more on cheaper guides.
They didn't worry about weight in the old days. The under wraps made the rod look pretty and more of a custom build look.
They put underwraps on surf rods and boat rods all the time On Tuna rods they even put double over wraps on them with an underwrap.
Fresh water rods didn't need them but till got them sometimes. Fly rods, they alway wanted them to look light as a feather.
I don't think Billy is braking your ____ . He is a real good Custom rod builder is trying to get his point across. Mike O is also a good flyrod builder trying to get his point across also. Ease up a little , these guys will help you. They have helped a lot of guys over the years. You only have 35 post? look at theirs. ?
I think what you described in your post was worded a little different then the way it came across.
