FWIW I find the Zero to be just fine with handlebars. Probably wouldn’t use it without though.
If you’re comfortable chopping your saddle up and making changes then there are many options. On my muni I have a Nimbus Gel which I’ve flattened somewhat and reshaped the foam. It’s good enough that I haven’t bothered looking elsewhere.
I got mine last year at Unicon, I guess it’s a v1 - sharp angle and hard as a rock. It’s good for the shaffing, but it’s a bit rough after 10k.
Roger refers to v3 in the video. I wonder where you can get the info about the changes, and the timeframe of those changes.

I found the Nimbus Stadium too hard. It was quite good for about 15 km, but after that not so much. I know there’s a new version out now that is softer and more rounded than the one I have. Roger talks about it here: https://youtu.be/YeEzvDxasLs?t=151
Soft and more rounded both sound like improvements to me. I have an older version; it was too firm, and the sharp edge chafed a bit.
The new gussets on the seatpost that Roger mentions also sound like an improvement!
My favorite saddle these days is the KH One, which I liked enough to buy another. I use them on my XC and road unicycles. For “real” muni I still like my semi-flattened KH Freeride Fusion best, for the extra padding.
I’m a newbie (just 3 weeks of exp, can ride shorter distances) with similar problem to the OP looking for a saddle for my first uni. So I’m just gonna post here.
So far I’ve spent couple of dozen hours on a QU-AX Luxus seat. Based on this I wish my own one was flatter and/or had a good groove. Whichever will help with not stopping the bloodflow to my junk and isn’t so confining for manparts in general.
Options that I have:
Kris Holm Fusion One
Kris Holm Fusion Street
Nimbus Gel
I’d immediately get KH Fusion One because of the huge groove and flatness but unfortunately it has a huge drawback of having kind of non-standard interface… Not cool. Still considering though if the others don’t suit.
How do these 3 compare to each other? (grooves/pressure on perineum/stiffness)
And how big of a problem this flat more bicycle style seat for a newbie really is? I’ve seen it mentioned here on the forums and KH site… Is it really that bad? Because KH Fusion One looks so much more comfortable than the bananas 
I don’t have a kh One but one of the stuffs that, I guess, increases the comfort for long rides (by avoiding, or at least delaying a certains kind of pain) is the very visible long hole in the center of the saddle (all the way).
Other Kh saddles (and not only kh saddles) have it dug in the foam but the cover pretty hides it and makes it useless.
I modified one of my fusion freeride saddles for the G36 (inspired by a tutorial from Terry) to make the tissue stay at the bottom (and dig the hole as well to make it larger).
It greatly improved the comfort.
Here is how I did this
I was given a One because the owner hated it. None of the the local riders like either the Zero or One and will gladly give away what comes standard. I thought I might try to un-flatten a One so I took a free One home with me. I still have not made any modification.
Finally decided to try riding on the One prior to ordering any new KH unicycles. After a week of trying it on short commute trips I decided a decent length ride was needed. It is not my favorite saddle but I managed 52 miles nonstop, almost fourteen hours on the One saddle, and 122 plus miles from Bellingham Bay to Artist Point and back for a decent one day test.
A few weeks later I did a 42 miles nonstop through Seattle during rush hour traffic. A little over three hours in the seat.
From my first ride on the One I have though it is horrible for the first mile. No worse for any length beyond the first mile. Many other saddles are great for the first mile and become progressively worse as distance increases.
Your experiences with the One more than likely will be very different from mine. Most riders quickly either hate the One or love it. To me the One is just okay. I’m smallish and one size doesn’t fit all. We would never tolerate only one size fits all shoes. But with such a limited market saddles are molded for child or adult. Take it or leave it.

I did give my feedback in another thread.
Firm? I also have a Zero and compared to that the Stadium is a marshmallow. Being used to ultra-hard bike saddles (and having been one of the pioneers of flattening saddles) I expected to like the Zero but didn’t for some reason. The Stadium is the best I’ve tried, but if anything I might choose for it to be a bit firmer. I presume I have a V1 as I’ve had it almost a year? In which case I guess I’d want to find another V1 rather than a newer one if I got another.
Should probably try a One at some point, but sad that my Zero probably has no resale value given I’d only get a One to replace it with.
I’d take One!
I tried Stadium, Zero, fusion freeride and street. I prefer Zero and I’m only one I Prefer it over Stadium which had huge flex. Only disadvantage of Zero Is, that it Is not compatable with reinforcement plate…
The idea is that it doesn’t need it - I’m running handlebars with mine (I presume most people with one have bars, it’s awful without).
