Nice shot Cameron ! I purchased and received my "Plamp" last week, and have no doubts, about it's usefulness. They are fairly "rigid", but I will agree, slightly over-priced. I googled "Loc-Line", which is the flexible tubing used, and found a plumming supplier, and purchased the same length of tubing, at half the cost. I also purchased the "pliers" to connect added sections of tubing, as anyone who has tried can tell you, this is some "tough" stuff. I bought some clamps at "Wal-mart" a year ago, 16 various sizes for $4.88, and some "chip-clips" for a couple bucks, and am going to put together my "home-made version" in the next couple days. When completed, and "tested", I intend on posting results in "Accesories". It is rigid and should hold most reflectors
with-in resonable size. Had no problem holding my "Sycamore Blossom".
