That's what Jerry Siem said, for those who don't know he's the head rod designer at Sage, and also built this rod himself. The rod was custom built on a VT2 blank but is a one of a kind with lots of custom upgrades including jade inserts.
I don't know. I have three YCX spey/switch rods and the color of the blanks matches that in the picture but then, Sage can do whatever they want. The blanks are all grey when they are rolled and they are painted so it very well could be a VT-2 blank.
