M8 Fat Boy Seat options
I was in the same pain as you, there was no way I was doing a week on the bike with the stock seat, I was close to tears after half an hour and an all day ride was excruciating. I couldn't wait for Ultimate so I went with Saddlemen. My tailbone is still sore I think from 8 months on the stock seat.

Definitely narrower at the front, feels like I sit lower.
Firm and comfortable.
Much better bucket (non-existent bucket stock) than the stock seat.
Not a lot of back rest feel if you are looking for that, but it is pretty supportive up to the small of my back . They sell one with the back rest, but the con is you have o remove the back rest when the passenger pillion is installed, so why bother unless you are strictly a solo seat guy.
The tuck and roll is minimal effect (more flat) which is fine for me the Saddle man has a real tuck & roll seat in comparison.
Passenger Pillion has a nice profile not real thick in the back, covers most of the fender, will be more comfortable for your passenger than stock. I think this seat is going to be just fine for me & it looks good to me as well. This bike is not my long haul bike so It will have plenty of support for the rides I take it on.
The Saddleman step up has a nice back rest, but the passenger pillion is really small & I didn't care much for the looks.
I've only got a few miles on it tonight & it's set to rain the next 2 days, but I'll report back when I can get a few more miles on it.
I'm pretty happy with the profile, not too obtrusive and still very supportive bucket. Just don't expect to be able to recline back and feel anything on your mid back, because it's not going to be there without the back rest, but the small of the back is very supportive.

You're bike looks great by the way.
Never would have thought I would have loved the white as much as I do but my wife was right again
