Mustang vintage solo seat.
I think that it feels better because it's higher as well as back maybe an inch or more. It definitely has more padding in it. I like the look of the CVO seat better so I will probably will keep it on for around town, but for longer trips the mustang has always been comfortable in my 09 Ultra. One thing I noticed though is that I think the windscreen is too short for me especially if my seat sits me up higher. I'll have to report back when I can actually ride it more.
Just questioning the stock seat on the CVO SG against your mustang, are you sure the mustang sits you further back?
i have the same stock seat on my 2014 cvo road king, its exactly the same seat they just upholstered it different this year and added gel,also its the same seat on previous cvo roadie glides, and i find this seat to be the lowest and most farthest back you will find on any other seat in the land,
granted not the most comfortable on long haul.
i also have a mustang sport solo on mine and be it more comfortable it certainly sits me about 1" higher and 1 1/4" further forward than the stock seat cvo seat that i have which is identical to yours in regards to dimensions.
Maybe your vintage solo is different to my sport solo?, maybe you could take a measurement please, would be interested to know the measurement from the bottom "corner"of each seat where theres a small upright in the seat back so to speak which is the furthest part you can sit back in it, and then from there to the centreline of the rear mounting bolts, sure would be helpfull buddy!!
