IMHO stay away from the HD pillow solo seat. That's what I have on the '03 Hugger now and I can't wait to get rid of that thing. 30 minutes in the saddle and my butt is tingling. I've narrowed my choice to either a Mustang vintage wide super touring or a vintage wide solo with backrest and a wide vintage recessed pad.
I'm leaning towards the vintage wide solo w/backrest and wide vintage recessed pad (for the Mrs.) because I'd have a backrest which in turn would allow me to ride a little longer.
Good luck on your purchase.
