Finally built the Eternity I picked up over a year ago. It's not nearly as powerful as I expected. To me, it falls more in the Lite/Fast spectrum than Medium/x-fast. It loads up pretty significantly when working a 3/8 weight. Much less powerful than my St. Croix 5S610MLXF. Feels more in line with my NFC DS610-IM.
It fishes nice and is super light weight. Balances well when paired with the Vanquish. I need to put it on a scale because I think it may be the lightest rod I've ever built (excluding ice rods)

Don't know where that holey cork ring came from. This was my personal stash of good stuff
