I got in on the group buy last year through the vulcan bagger forums.
This is the vinyl, half-moon, basket-weave on a Tiger Explorer:
It sure makes long hauls much better. Confirmed this on rides from NH to GA and back (BRP, etc), and another from NH to OH and back. Some may laugh at a saddle like this on an an adv bike, but I use it for touring/motocamping and appreciate the comfort.
edit: I see fammdw two posts up - he orchestrated last year's group buy with RDL. Thanks for the time you put in on that Mike!
