I totally agree. SL tech was a step ahead of 3025 and a step behind Clan tech. It didn't take long for the IS to master SL tech once scientists were no longer "committing suicide" and teams were obtaining plans and samples and open the tech floodgates.
Define Not Long?
The NAIS had a copy of the core sometime between 3025-3028?
It took them till 42 to figure out how to make a SFE w/ DHS inside it.
Which is something they already knew how to do in the past, they just had to get back up to speed w/ tech they had forgotten.
The Snubbie took the DC till 3067 to create because it wasn't a common item for the SLDF in 2780 & was only in the prototype & initial testing on a couple of designs stages.
What I was referring to are the weapons used when the Clans first invaded the IS. They went from Improved SLDF Tech and prototypes of what the IS is using now, in Operation Klondike straight to Clan Tech in a few years. In some cases the research was happening at the same time. I would have thought there'd be a period of time where the Clans would be using what the IS is produced in the 3050's before upgrading to Clan Tech.
While I don't care for how quickly clan tech was developed, I think one of the reasons behind that speed was that the clans didn't just have TRO2750 tech.
They had access to the best R&D stuff that the TH was just creating at that time.
So stuff that the clans had Prototyping like ERSL/ERML/Streak4-6 were probably things that were current R&D for the TH at the time.
They had the Snubbie stats.
They probably had some ideas on how to make Endo/Ferro less bulky but it wasn't even at the Field Testing phase like the Snubbie was.
They probably had early research into the "Improved" ERPPC already so it was just spending another 20 years to bring that from SLDF R&D level to Clans-Prototype level.
The IS on the other hand in 3025 were below AoW tech levels in the case of JS/WS technology & barely holding onto Intro Tech w/ all the old half repaired w/ flaws notes in the scenario books & fluff about certain DS engines no longer being able to be produced, etc etc.
So you get a house that can "barely" maintain intro tech & you give them a tech manual for SLDF tech.
It took them years just to decipher it all & then years more to prototype it.
The early 40's we start to see the first mechs using this tech coming off the production line & even then it was just a few models as test beds.
The stuff the clans had at the beginning was R&D the IS hadn't even seen yet at the time.
The houses had some SL stuff but they didn't have legions of Royal class machines & certainly not the very best stuff the TH had been working on in the 2700's. Stuff in TRO2750 had it many cases been around for centuries.
If the Amaris crisis hadn't happened you would have seen the SLDF moving up to Clan Proto & IS-3060 standards by the end of the 2700's I'm sure.
The Jihad & the ROTS "Peacetech" also stopped a lot of the innovation that was just hitting in the late 60's.
I can see why only certain manufacturers are making Clan Spec in the dark ages.
They had suffered a lot in war & then stopped a lot of advanced R&D in order to get basics like food production, water purification, & JS transportation going again at full levels.
