From a quick check, I haven't seen a thread outlining this for you guys, so I thought I would send a quick message. I am not interested in debating whether this should be an AS component, or a Tailor one, or how much you should charge, just what to experiment and what kind of materials you should worry about.
First, from all looks, it appears that the Encumberance on this armor is very low, owing to the fact that it is only 4 pieces per suit. For this reason, you need not concern yourself with the durability experimentation line of your construction.
Armorsmiths will be looking for only high stats from the QUALITY line. For this you will need materials with high OQ and SR. This shouldn't be too hard. Take note of the percentage experimentation you get up to on this line, and name your crates/schematics according to this percentage (IE: Padded Segment 93%). Once you pass 75%, it will provide 4% base which all armorsmiths will want at the least, but if you can get up to 90% or more, it will sell better (even though it still says 4% base, there is a hidden fraction which can help us make better stuff sometimes)
I might suggest scaley or bristley hide for the unnamed hide slot, cause you can usually buy it much cheaper than the others, and with much better stats oftentimes too. But the best hide will be what you want to use. Wooly is usually difficult to come by unless you hunt it yourself or hire a ranger. Fiberplast is easy to find with good OQ and SR.
If you have extra points after maxing Quality, put em into durability, but really this won't make much difference to us. Hope this makes it pretty clear what to experiment on, and what kind of hides you need. Good luck.
