IMHO You are looking at the right brand. I bought a Stingray last year. It has been put to the test many times by me since then. The ability to layer up and down is a great thing. Please narrow your search to the shells with a powder skirt. I used mine quite a bit last year. When I didn't think I would use it at all.
I just picked two Arc mid layers.Apache and Convert. I could have used some of what I already own. But Arc stuff is designed (almost engineered) to work together. With less bulk and an ease of extreme movement.
It all starts with the high quality materials and components they use. Then the ergonomic cut or tailor of the piece. All followed up by the way it is sewn together with a close attention to detail.
People complain about the price of Arc. OMG! That's crazy! etc.
If you can afford it. Remember! Your not going to have to replace your purchase for many years.
If you can't afford it. Look close at it. Notice the materials, cut and the way it is assembled.
Find something in your price range that comes close to the Arc.
I have the Patagonia main store near me. Some of their top line now looks like Arc with the same prices. They too know about Arc.
