Let's not get crazy here, I don't leave home for long (pavement) days on any bike with any seat without my Airhawk.
It's just that good comparatively, even with a big custom saddle like on my road bike. Some habits are hard to break, the hell with how funny it looks to have one a on dirt bike, my butt thanks me.
I spent all day riding on sunday sitting down half the time and had no issues with comfort on the SC seat, but if I had to bang out long highway miles I would have brought the pad.
I don't want to give the impression that the SC needs a pad to be comfy, it's just my way to travel.
Looking forward to your comparisons since you will have all the pieces.
