Hi

ISM saddles just come out in France, I use the Road. I find it v comfortable compared to traditional saddles, it does make you use your leg muscles in a different way, all the weight is basically positioned on your bum, so it works your legs! On the plus side you don't get the same discomfort/ numbness.

Its not cheap (89 Euros i think, don't know what it is in $), so if our discomfort is marginal, not sure if all people would go for it - but I am happy with it.

Anyway, hope that helps
