I have a NoMorFlats on the back of my bike.
Clotho's Bike
It rides a bit mushy but it doesn't go flat anymore. I found after awhile that I grew used to it. I still check the spokes for tightness and the rim for straight, from time to time. So far so good.
My front tire was never a problem so I left the tube in it. I just put the NoMorFLats on the back. I think that the handling is a bit better with the tube in the front than it would be with a NoMorFlats up front.
Where did you find your NoMorFlats?
