Comfort is a very subjective thing so I'd take whatever I heard here (or anywhere else) with a grain of salt. I've owned one cruiser, an HD Super-Glide, and it really doesn't compare to your bike because the pegs were mid-mount. That said, HD mid-mount pegs are still well forward of where the pegs mount on most bikes.
I rode the bike a lot, 54,000 miles in 23 months, and it was ok but I found this:
Back comfort. That slouch will eventually bulge disks in your lower back because your back is designed to curve in, not out. I know, I know......"doesn't hurt my back to slouch". Not yet it doesn't.
Butt comfort. Without being able to weight the pegs and relieve pressure now and again can make 150 mile + stretches a pain, literally. Not so important on the HD because that was it's range. The DL can go 200 miles a pop, easy. I have always been a firm believer that the seat and postion should be comfortable enough to ride to reserve, tank after tank.
Control. You just can't believe what having the pegs underneath you can do for control. Imagine trying to ride a bicycle over unstable terrain and having your feet out in front of you as opposed to being able to stand/or weight the pedals more than the seat 2-3 feet above it.
I've owned and ridden motorcycles continuously for 38 years. Of them all, and I've had some nice ones, the DL650 is clearly the best. But like I said before, that really doesn't mean anything because it's what I think, not what you think.
If loud pipes save lives, how come so many people that have em' crash?
