I've been using the thread on gates belt cog with no issue what so ever. That said I do have two small spacers on in-between my hub (Mack superlight) and the cog to ensure the belt has a dead on straight chain line.
I'm using a standard lock ring to keep the cog in place. You can find lock ring tools that look kind of like pincers that can be used to fit it on properly. Useful when trying to tighten a lock ring that is in a recessed place.
