I havn't ridden one but it is a dyna so it will ride very similar to a dyna. The fat front tire tends to ride smoother and softer than a narrow front tire so it should ride better than a standard dyna. As you probably already know, dynas tend to ride a little smoother than a softail, but not as smooth as a road king or electraglide.
One thing I would like to point out...I consider the switchback and the expansion of the dyna line to be an indication that the softail craze is beginning to wane just a bit.
