I'm interested to see how this blanket/belly pan thing shakes out.The only thing I have ever run a blanket on was a glide.
If the belly pan only has to be 2" deep and doesen't have to have a cert. I really think that is gonna be the hot ticket for most of us.
Most of us have or have access to a tinbender and even though it may take a little longer to engineer in the long run it would be easier and cheaper for the bellypan(because it can be made per app.).
It also will help with the aero aspects too,although that's prolly a moot point for the most part.
