I even went seeking out the same areas that were guaranteed to flat... I was using the 20x1.75 size .. I think Jur was using the 20x1.35 .. don't know if there is a difference in individual construction between sizes, but mine have been terrific... they are the heaviest Schwalbe tire out there, but you're geared low and do a lot of trails.. might be worth a try.. I don't like flat sealants either..
