I had a mini panic attack because you dudes made me realize that my new 2010DR (based on my MDR's measurements) is longer than my old 2010DR.
.. and then I realized that it's only going to be longer by half an inch, the same amount the dude with the perfect fit wanted to take off. Not worth "adjusting" in the end, because the effect will be pretty much negligible - this pair will barely cover the waistband stitching on the top of my pants.
I think that you can go with a jacket that's long enough to completely cover your jeans waistband with the MDR&CM, but it's not my cup of tea. I would hate to do that with a 2010DR or a moto - I prefer these styles cropped to exaggerate the V shape of the jacket.
