You can check your comfort and ergonomics of the motorbike using web page http://cycle-ergo.com/
You can choose any motorbike and input your own dimensions. You will know angles of your knees and hips. If they are more or less 90 degrees - you will feel comfortable.
Checkout the Roadsmith Comfort Controls .... (do a search for Roadsmith on the forum).
The extra couple of inches and the extra adjust-ability of the shifter and brake are great.
I Also added Ergo II's to help.
Russell day long, custom to what to what you want.
I agree with Rich...Ultimate King seat will be good for you. I wouldn't recommend the Mustang seat for long seamed riders because it does lower you down one inch...which is not something you need. You may also want to consider a custom seat...such as a Day-Long Russell seat...they can add springs and make your seat taller and back more. But with a taller seat, you may need to get helibars.

There is no getting around the fact that the cylinder heads occupy the same space your feet really want to be. That is why I sold the six after 360 days and 9000 miles of terribly uncomfortable ownership. I got a Moto Guzzi California 1400 and much prefer it. I'm an ex Victory owner and they are the most spacious bikes made.
