Morning Icosahedron,
I dabbled in FF&S, too, but as Sabredog says, it was a bit too gearheady on the whole. My main use for it was in designing sidearms for my characters. Anything bigger than a sidearm was just too much trouble.
Yep, FF&S is an even more gear head version of Striker and a more extreme version of the design systems found in CT: Starships and High Guard.
To be honest I've only figured out bits and pieces of Striker (until now anyway

), MT: COACC, and FF&S for TNE and T4. I've even figured out bits and pieces of the MT: Wet Navy (Challenge Issues 53, 54, and 60) and early tech design (Challenge 61) supplements.
I've been using a combination of GT: Starships and GURPS: Vehicles a lot more to design custom and modify standard systems. Of course the designs
have not been imported into CT, MT, TNE, T4, T20, or MGT. I tried and decided the process was too much of a headache for me and I'm just too lazy

.
Even Striker's CPR system (and its aircraft system) was too much like hard work - hence I haven't really been following your CPR designs. I preferred designing vehicles, lasers and energy weapons.
I'm going differ and say that Design Sequence 1 Vehicles is the one that is like too much work and that the twelve other design sequences are just varying levels of work.
To me the design process for an aircraft appears to be less time consuming than a vehicle, while determining the ratings appear to be about the same level. Of course I'm still working on through Design Sequence 1: Vehicles and got side tracked on Step F. Weapons.
Don't worry, I'll be putting up tests for lasers and energy weapons in the future which appears to be in any area you have experience and interest in.
A word of warning on designing FF&S sidearms, though - the rules are made for longarms - if you want to design realistic pistols you'll have to ignore minimum receiver and barrel lengths and then make up some sensible figures for muzzle energy, etc. The thing is definitely broke for pistols.
Thanks for the heads up that the small arms design sequence focuses on long arms. I think that Guns, Guns, Guns, 3G^3 for short, by BTRC maybe worth a look for pistol design. I know the book has a section on converting 3G^3 to Traveller. Specifically the first printing of the 3rd edition has the process to convert to MT and the second printing can be converted to both TNE and T4. MT was dropped in the second printing.
Of course compared to Striker 3G^3 is a lot of work. The design system may even surpass TNE/T4 FF&S.
Once I figured these things out though, I had great fun designing weapons and then drawing them up with... Drat, what was the name of that online gun designer? - you can tell it's been a while.
If you recall what the name and where the online gun designer application/program might be found can you please let me know.
Thanks for the reply,
