One recent review of note, Andrew Steketee of Flylab does a deep dive on the Epic Reference 686 that is worth a read. I've said it for years that this is the glass 6-weight from which all glass 6-weights are judged and this review is required reading if you've been considering this fly rod.
Want options? The Epic 686 is offered as a Blank, Build Your Own Kit, in the Reference Series, or as a Reference 686 Combo with a fly reel and fly line.
There are a handful of glass fly rods that I think everyone should own and this is one of them.
