For those of you who might be interested, I tried the BMW Rally seat on my bike for several thousand miles and found it a great deal more comfortable than the stocker. It adds a bit of height and is narrower which makes standing easier. The foam appears to be firmer as well.
In the end was still too low for my comfort so I purchased Yeti's custom XPC which seems to be a much greater fit for my 36" inseam.
The Rally seat is up for grabs in the flea market if interested.
