Glass tends to be tougher than graphite. The Echo is great for dry fly but is very much a through action rod. Nice even with 6"wbt - bends through to the handle. Might not be the best rod for nymphing though imo.I have never used "glass" so don't really know. I intend to use the rod for dry fly and upstream nymphing. Silly question but is glass more susceptible to damage from beads if hit whilst casting. I still manage this occasionally.
