Several reasons have already been posted as to why builders are going to fixed gear. In additional to the original gear being unreliable, the fixed gear is several miles per hour faster and lighter by several pounds. I firmly believe there is not a KR out there that can make a "full stall - three point landing without the tail touching first. Even a KR2S tri-gear on Diehl gear will probably touch the tail without fully stalling the wing. I had a tri-gear pilot attest to that fact on one occasion while discussing full stall landings.
