Gates "Surefit" sprockets for belt drive bikes

I guess this has been around for a while, but I just noticed that Gates now sells a new rear sprocket called "Surefit" that features a new design that makes the sprocket fit flush with the Nexus/Alfine hubs. The biggest (and probably only) problem I've had with my carbon belt drive train is a clicking noise that results from the sprocket not interfacing well with my Nexus hub (there seems to be a small bit of play between the two components). I wasted countless hours trying to chase this noise down only to find later that the answer was already on Gates' FAQ page along with a remedy: wrapping teflon tape around the hub-sprocket interface. The tape method seems to work, but I've found that I have to periodically re-wrap the interface with fresh tape to keep it quiet. Looks like they made this new sprocket specifically to address this issue. Has anyone tried one of these yet?

I'll ask some people. I'm going to be converting to belt drive if I can swing the funds, so this is of interest to me.

I'd also ask in cruiser forum.

You do realize that belts are continuous,right? You need to have an opening in the frame to slip the belt through.
