If you own Original Trux and they're set up how you like them, there is no published reason here to replace them. A 0.7mm height change and a 0.6mm wheelbase change is a preference adjustment, not an upgrade path, and FlatFace hasn't framed it as one — no claim of better materials, better tolerances or a new axle design appears in the listing.
If you are buying trucks for a 34mm deck for the first time, or you already know you want a slightly taller setup and a tighter turn, Type 2 is the current model and it ships complete with bushings, pivot cups, hardware and a tool at 43 to 53 dollars depending on finish. The Standard finishes sit at the lower end of that range; you are paying the difference for Hex Hybrid and for the colorway, and the listing does not claim any performance reason for it.
The caveat on all of it: everything above is geometry on a page. Ride height and wheelbase interact with your bushings, your deck's concave and how hard you set the kingpin, and none of those are constants across riders. If turning feel is the thing you are chasing, a bushing change is the cheaper experiment to run first.
