I'd keep this shoot out solely for bikes and not add the complexity of different clothing in there though, there is more than enough anecdotal data on different forums on people who tested with different clothing..

I would also be interested in donating 25-50 dollars, and I'd happily take days off to help out but I'm in Belgium so unfortunately that will be very difficult.. Is there a way to set up some kind of gofundme (I have never used one so not too familiar with it) for a certain period and see how much we can come up with to see if it's feasonable, else either the test is cancelled or the scope has to be reduced? And I guess the scope (i.e. which bikes) we would like to have tested needs to be set to get people to invest.

What I do have some difficulties with is some people funding quite a bit of money or offering up a lot of their time and then likely have 10x the amount of people that will read the white paper but not have contributed.. The results and paper should only be available to those who contributed either financially or by providing bikes/equipment..
