I recently bought a 29" with 3" wide tires. It's wheelbase is very long. Tight switchbacks are very difficult for me to ride without putting a foot down. Handling seems less finesse and more barrel over the top. I can bust over the top of terrain that would have pinch flatted my 26er. It's very comfortable, but definitely more awkward to ride in technical terrain. I'm still glad I brought it. It's going to work very well for bicycle packing, but I often wonder if it'd tackle technical terrain easier with 27.5 wheels.
