CG,
very well done. I've been playing around with QS's also and have to say they are pretty impressive. One thing I did notice on one arrow that I was shooting with a partial detached vane (poor gluing on my part) cause the arrow to fly at a right angle in to the target. You would have thought the arrow was bent if hadn't been a carbon. Took me a minute to find the problem, but it was a little weird that just having an air gap could cause that type of problem. I've noticed no real difference in noise (shooting outside). I'm shooting minimal offset maybe 1 degree and they are flying perfect with muzzy 100 grain 4 blade broadheads.
