Thanks everyone for such quick feedback and information. I've decided to go ahead and purchase the 2018 Stella FJ 2500. Although the Daiwa Exist LT sounds like a nice reel too, as well as other Shimano product lines...
It does seem the Stella FJ series (Stella FK?) is due for an update. In addition to perhaps a lighter reel, I would assume it would inherit some of the features from the Stella SW C line such as Heatsink Drag, X-Rigid titanium bail, X-Rigid Gear, etc... We'll see.
