I have the TODD'S canopy. on my KR2. It is VERY flexible, and op[tics are fantastic.
My KR2ss I'm building, I found a tinted Zenith 701 canopy, very large but cuts down to a perfect fit, it is round at the back, but this time I will be flattening the top as it is very flexible as well. Phil Matheson SAAA Ch 20 http://www.philskr2.50megs.com/
