I also changed to the K&N...will have to try the bag or soda bottle method to catch the mess next change.
Concerning the tranny...what I read said it was different than the one offered as a replacement for the 5 speed this year, whether you bought the whole tranny, case and all, or just the gear set. This new one has helical cut gears instead of straight, as has been the traditional configuration for oh so many years. Did last year's Dyna have this same gear set? If not, we are looking at a totally new product here, unless I read something wrong. The new gears would be inherently quieter, and smoother shifting well...perhaps even more efficient in some regards. But, it's the first year of production unless it was used in the Dyna last year.
