I have only ridden them around the neighborhood a few times because i've had a fractured femur for a couple of months now as result of being rear ended by a careless driver. That said, i haven't noticed any of the characteristics you mentioned. They roll as well as my 35mm Panaracer T-serves if not better. I have not noticed any abnormal tire noise or steering abnormality but i haven't been able to go fast.
Hopefully, in a week or two i will be able to go for longer rides and see how they really perform. When i do, i will make sure to watch out for the things you mentioned and will post about it in the forum.
