The "wedge" windscreen is available from Airplane Plastics, 937.669.2677, speak to Jeff or Becky. They are indeed the suppliers of Van's OEM canopies and are very nice folks to deal with. I've already purchased the windscreen and intend to use it whether or not I lower the canopy. Those of you who were at SWRFI this year got to see Lyle Hefel's plane with this windscreen on a standard height canopy. This was the plane that inspired me to pursue this mod. I'm still undecided about lowering the canopy, but only from the extra work standpoint - at 5' 8", I definitely won't have a head clearance problem. Due to the rake and extra thickness of this windscreen, I feel that it is certain to be more bird resistant as well.
