I just went through this a few weeks ago. Essentially looking at a highly reflective streamer as an alternative option for a drogue. I have yet to test it to see if it behaves as desired, reflective and keeping the nosecone/payload section above the booster on decent. I am hoping to test it at NYPOWER, if so I will post my results for you.
In doing my research I came across the Shadow site while in discussions with Gary from Top Flight, not realizing he made them. I ended up getting a 3"x72" reflective streamer from Gary. And he has a small amount of fabric left to make more, including custom lengths. Originally I asked him to make me a 5"x120" then realized it would not fit in my payload bay.
While talking to Gary he did say what others have mentioned here, in that the fabric has gone up significantly in price, I think partially due to a min order size, to the point where he felt he would not be able to charge enough to make it worth his while. Incidentally the streamer is beautiful and should pack well.
I also had Pat @ Dino chute make me a Mylar reflective streamer which I will also test, however the Mylar has to be rolled or at a minimum folded neatly so if your payload tube doesn't have the space I suspect that the fabric is a better solution. Then there is wear, the Mylar may shred but Pat really did a nice job in protecting the edges in an effort to mitigate that, so who knows which will perform better...some launches will tell.
