Did you notice how there is no air coming up your legs and hitting you in the chest with your feet on the highway pegs? I did and to me that is a big improvement...really no difference down on the floor boards or up on the pegs! I agree with all your other assessments. It keeps getting better.
We ran 300+ miles today. Lots of twistys and about 100 miles on the interstate this evening to get back. When we got back to the cabin, we both were excited about the ride and nowhere near wore out. The bike just sticks in the curves, handles the bumps well enough (for us, about 320-325 pounds between the two of us plus rain gear/leathers, tools etc) and eats up the miles in the super slab. Wind is really nice. Enough but not tiring. As you said, feet on the pegs, which is how I rode 99% of the interstate, and no wind kicking your but.
My wife usually is leaning on me several times throughout a 300+ ride and mainly on me by the last 60, but not today! At one point on the curves today she leaned up and said " from where I'm sitting, this bike handles even better than the red bike" ( our 2011 RG Ultra). We both agree that this is the best bike all around we have ever owned.
