1 star 35 durability rotation

[Roth_Trailfinder]

Arkfrost, use Manipulation instead of Master's Mend. It saves you 4 CP as long as you know how to use it. Basically, use it when you would a Master's Mend, then drop NOT use a Durability consuming move immediately after.

That said, if it takes you 5 CS2's to do the recipe, something does not seem right. With 995 Craftsmanship (on a non-specialist) I'm getting 144 Progress on an unbuffed CS2 on one of these 1 star recipes. That means it should only take 4 CS2's at this stat level.

Anyway, CZ, IQ, CS2, SH2, WN, HT, HT, CS2, HT will get you down to 5 Durability.
Manipulation, SH2, WN will bring you back up to 25 Durability.
HTx4 will bring you up to 35 then down to 15 Durability. CS2 will bring you down to 5 Durability.
Manipulation, SH2 will bring you back up to 15 Durability. HTx2 will maintain at 15 Durability.
GS, BB, CS2 will complete it.

I count 9 HT's, but this leaves me with less than 10 CP and I started with 430. This does not buff the BB (beyond GS/SH2) nor does it buff any of the CS2's, but at least it does not cost 494, which is what I count up magnanamousCynic's rotation to cost.

All this aside, play around with Rath's on the 2 star. I think you'll find that you do not really need a lot of HQ for the carbonweave stuff. If you can HQ Luminous Fibers with only NQ materials, then the same holds true of any other 2 star recipes. You might consider trying just an Ing2->CS2's rotation and taking the NQ, especially if you have little trouble HQ'ing other 2 star recipes.
