You are in a similar situation to where I was, albeit I came off a slightly more powerful bike (BMW S1000R), but the same riding style. The switch to the SSS was huge for me. The seating position is a perfect blend of sporty and comfortable at the same time. As a nice bonus you get the looks of a super bike, without the pains.
In your case I suspect you'll pick up a bit of performance from the 696, but expect to feel like some of the edges were softened. The SSS just feels more a part of you than almost any bike I've ever had. It truly inspires confidence in turns and general riding. Best way to say it - the bike feels a part of you. Highly recommend it!
