Arzuna or reverse look?

Since you're likely to maker both of them, depending on the crystals and scrolls you use, you could miss out on 5 or even 25 stats. The real bonus of the reverse stuff is that it levels up, so you get extra stuff. The shoes and overall are the only other timeless things i could see a bowman making besides the weapon.

The average stats will show up if you hover over the picture in item maker =)

I'd go for whichever you could afford. Since you have some NX, you could always cover that up too?

Here's the Sticky in Training Grounds section shows practically everything you asked for :
