A 29er with plus tires is a pretty good all arounder. As said decent fork, hydro brakes and bits. Can always run smaller tires if needed. What do the locals run on your trails? What katsup said is a good start. Got any bike event where you could demo some? Bike shops should get you set up to do a ride on dirt. Think 1-1.5 K new. The new boost spacing with 110 front and 148 rear hub width is just from the last 2 years or so.
