I built a rod on one of their 15-foot, 10/11 blanks. It's a medium-speed stick with a DT11 line, strong enough in the tip for sinking tips and larger fly. Nothing exceptional or exciting about it, just a very useable rod in its size range.
I've also fished briefly with a friend's 14-foot, "9/10" model. It's easily the stiffest rod for its length that I've ever used. Its rated lines were too light; it took the above DT11 to make it perform, as a very strong, medium-fast action.
