The solo seat will move you back and down quite a bit, it will make your reach to your bars about 2 inches further, I like mine because I always felt like I was riding on top of the tank. I think you will eventually want to ride with solo seat once you see the difference, and it takes no time at all to add passenger pillion.
 \\;I got the Mustang solo w/backrest and 11" passenger pad for my 08 SG. Very comfy. Torn between Corbin &\\; Mustang, chose the Mustang because of all the positive press from this site. \\;
I suggest heading to Hollister to Corbin's factory. They take walk up's, better to call and make an appointment, in the mornings. You pick the seat, they mount the hardware and seat minus the leather cover, \\; and you take it for a test ride. When you get back, you can make all the adjustments you want and they will do it right there for you.(shave off foam to lower, add to make seat wider or higher, etc) Once you're happy, they will install the leather cover and even give you a $5.00 coupon towards food at the Cafe.

AWESOME people and QUALITY product. The seat being lockable is also an added security plus.
