Gone further nuts again..
I put one of these on today:

dddd pointed out a while back that 7 speed and 8 speed cassette and freewheel spacing was a little different:
http://www.bigboxbikes.com/viewtopic.php?f=14&t=4314&p=47572&hilit=+cog+spacing#p47572
I had been running an 8 speed shifter on a 7 speed freewheel, and it was never exactly perfect shifting.
But now with 8 speed shifter and 8 speed freewheel, it's dead-on with every clicky.
The problem now is, I really want to change the cassette on my gravel bike from 7 to 8 speed, but it's an older 7 speed hub, and I don't know if I can get a wider hub body, but I will be finding out soon. Shifting a 7 speed cassette with an 8 speed shifter on both bikes has worked for me, but somewhere in the middle, it just isn't quite right. Out and riding, it tends to ghost shift and delay in the middle range gears. Sometimes clicking twice to get a shift down to second, then one click down to first, it takes 2 clicks to get back to second.. then it wants to jump to 3rd when I least expect it. Irritating, but I dealt with it.
So, Thanks dddd... You have me convinced that I need to spend even more $$ :P

Anyway, I've decided to go with Microshift 8 speed brifters on the new handlebar on the Malus, and this new freewheel has me pretty pumped about getting it all together and getting some rides in before I hit the beach with it in November.

Ha!
I have everything except, the handlebar. I ordered it from a company I hadn't ordered from before. Apparently they're extremely slow. Will update as soon as I get it all together.

But as far as update goes, The 8 speed freewheel is awesome! And the MicroShift brifters are here. The have a very good feel to them, bigger than the Shimano shifters, but appropriate for the fatbike, and the replacement hoods are in the $6.00 range. Dying the bar tape tomorrow to match the seat. Will see how that goes too.

This one is becoming the build of the year, and it's still progressing!

I'm wondering how you ever found a QR rear axle that was long enough for the wheel and 8s freewheel(?).
Would a solid 10mm axle be available for this? I guess it would have to be well over an inch longer yet.

One thing that makes the heavy OEM tires good is that their thickness and stiffness allows lower pressure while providing more damping versus a supple tire at higher psi.
My Huffy had a bouncier feel to it after I changed from the Hondo's ChaoYang PLUS tires to the lighter Vigilante tires that needed about 50% more air pressure to prevent wallowing and pinch-flats, but of course the bike did also become lighter and faster-rolling. Traction up and down hills also improved, due mainly to the deeper tread.
I just changed the rear tire to a Maxxis Minion DH tire, and with lower pressure again I am back to a softer ride feel and with the very tall tread the traction is better than ever. I actually found a pair of these expensive 27.5x2.5" tires in new condition at my local Goodwill for just $5 each!

Nice work TC. The details always help. I just bought a Mongoose Hitch myself. BTW - I think the Malus & Hitch share the same frame. It's not quite the same as the Dolomite. The Dolo's axle is bent & front & rear bearings & headset are shot. It's been a long 3+ years. I waffled for a while & considered what you've been doing with the Malus vs. just putting the wheels on the Dolomite & replacing the BB bearings (and transferring the rotors & mega freewheel). Ok, I'm still waffling as I review this thread again. Darn you for giving me the upgrade bug again. Hope I come to my senses.
