So yeah, the satin polyester looks best on lighter color woods like Maple. That being said, the gloss brings out the most in the wood. Satin polyester on dark woods shows trapped skin oils in the fine scratches that form the satin rubout. The manual buffing process on this finish takes decades - it's really hard stuff but it will get shiny where you touch it the most.
The Orion guitar (and Epic, Orion, and Excel basses) originally had a polyurethane "Satin Natural" finish that sort of mimicked an oil finish. As Vince stated, it does buff up over time where you touch it most frequently, and we no longer offer this finish (actually the manufacturer discontinued it shortly after we stopped buying it so nobody uses it anymore).
Like Keith said, oil also shines up where you touch it a lot, but you can wax it or even reoil if needed to restore the original look. With an oil finish, you don't have much protection for scuffs and scratches to the wood.
We use our classic polyester finish which is the same since 1981. The standard is for glossy body with a satin neck feel, kinda best of both worlds. If you want the satin all over or the gloss all over no problem and no charge.
