My first good trout rod was a 1972 Lamiglas 4wt that I still use occasionally .
If it's wasn't the slowest fly rod blank ever made, it's right up there. So there was only one way to go.
When graphite rods came out and then got progressively faster, I stayed stuck in the '60s so to speak and never really switched over. Only a couple of the trout-weight graphites that I own get fished regularly. I still fish fiberglass for the most part in fresh water, but just not with rods quite as slow as the Lamiglas.
