The Bailout cassette appears to address these top end gaps at the loss of the low end range (which I think I can live with) but I can't find anything on the net about its performance in the 9T sprocket and how it shifts. Its also unknown if the SRAM X1 X-Horizon long cage rear derailleur I have now would work well with the smaller cassette.

I actually had a Zee derailleur and 11-36T cassette on a Dahon Speed D8 and it worked very well. That bike is fitted with an Alfine 8 now though.
