Nice work plumbob. It's been years since I have built on an Elkhorn blank I didn't know they were still around, they had some nice blanks with some great color availability I do remember that.
I had built a rod for my daughter using an Elkhorn blank and really liked it. Like you said they kind of vanished, had looked around to try to find the color I wanted but wasn't happy with any so I tracked down Elkhorn, they showed completed rods but no blanks so I called them up to see if they had any old inventory. They said they had the 5 weight in purple and a 5 piece 3wt, so I got them both since I generally use a 3wt and wanted something that packed a little smaller.
