Great, I'll give this a try! Sorry that I've taken a while to reply, I was rendering the bottle glass with the gather on it to put up here just because it has an interesting look to it. Yes, it did slow down render time. As I said, I was using your orb shader for thin glass on my bottle.  However when placed in the larger scene where the bottles were just a small element, the glass didn't render as well. But I'll admit, on the earlier trials of the larger scene, I had not placed your Evosphere into the studio (even though the Evosphere is not seen at all in the scene, I realized that the glass needed the Evosphere to reflect off of).  I think if I'm doing a render such as this one with just the bottle, or a grouping of glassware, then the Orb Shaderis perfect (as long as something like the Evosphere is in your studio even tho not visible in the render scene), but if the bottles are just incidental props then maybe I don't need true reflection/refraction.
