Like most other folk, I filled out the on-line free sample box and then forgot all about it. However, it appears Norway Ind. didn't, and a little packet arrived this morning with $1.18 postage on it and nine vanes inside.
I am fletching them onto some spare Lightspeed 340's and we'll see how they go.
I'm more interested in flight than visibility, but I can think of more than a few shots that I took at a heavily wooded 3D comp yesterday, where it would have been a huge advantage to have been able to clearly see where my arrow had landed (or even the target on a couple of shots!).
