I suspect the TL tree progression will follow the same lines, thematically, as the tech of the Star Fleet Universe as is. TL is a relative indicator of sophistication with some number or label thrown in for distinctiveness. As an example, Prime Directive D20 Modern version did not follow the Progress Levels to match those found in its D20 Modern SRD or in its tech assumptions. You have to do that with SFU/Traveller TL. One of the SFU warp speeds is a 500pc in one month? Better than TL 15 Warp Drive (24 pc per month, pg 109 Alternate Drives). "Transporters"/teleporters do not even exist in the Traveller Core Rules as a tech device. Neither do "tractor beams".
I'm fine with that as long as the values for "existing historical TL" (0 thru 8 ) remain the same, and that future-tech found in the Traveller Core Rules (cause all you will need is the Core Rules and Prime Directive, right :wink: ) is TL'ed to conform to the values found in Star Fleet Universe or outright stated as to not exist in the Star Fleet Universe. Oh and things that don't exist in the Core Rules, like transporters and tractor beams, are fleshed out to conform to the rule system as best possible (like ranges/skills needed/costs).
