I'm not sure there is a perfect bike. I'm much bigger than you, GoodOak, but I'll share my experience anyhow.
First, I demoed that Stache 29+ in Marquette and found it so fun, I kept it all day. I really recommend trying it.
Otherwise, I'm down to only two mountain bikes these days.
I have that salsa mukluk with 2x9 white brothers carbon fork and a set of Nates that I use in the snow and at blue mound and for touring and other places where gears are an asset.
Most of the time though, I'm riding a 2014 kona unit rigid steel singlespeed 29 that I got about two months ago at trail this. It's mostly stock, but I've upgraded to carbon bars, esi chunky grips, and tubeless maxxis ardent tires (2.4 in front) to soften the ride. I recently added a salsa flip lock seatpost clamp to provide the ability to lower the seat for pump tracks or raise it for a bit more efficiency along the military ridge. Mostly, though, I keep the seat at a reasonable height for trails. I've found this bike pretty much perfect for me, pretty much everywhere. It rips at quarry ridge, Seminole, Blackhawk, pleasant view, cam rock, kettle, Levis.
I thought I wanted a steel singlespeed (possibly a honzo) with a suspension fork until I rode the unit. I knew instantly the unit was the one from a quick parking lot ride and bought it on the spot. It just felt right. And it still does. Maybe even better with every ride. I hope you can find the same.
