Get a good ride on a tallboy. Each time I ride mine I’m surprised and excited by how good it is. It is my first 29er and I was sceptical about the whole 29er thing (especially as I’m only 5’8″) but the bike is simply fantastic.
I’ve used it in whistler on some of the world enduro descents (but not in the bike park…), the Alberta Rockies and the long trails in southern Tahoe – all very different but all pretty demanding. The last time I was home I rode it around leath hill, etc and it was fun there too. I currently live in the very flat Huston. Surprisingly there are mtb trails, even in the city, the TB is fun to ride there, too.
I will say that a fox 32 at 120mm it too flexible, I switched to 34s. The addition of light bicycle 35mm rims was a great improvement over the 19mm inner width rims they replaced. Don’t know if it was width, weight or stiffness that made the biggest improvement.
In summary, try one. If you buy one get a sturdy fork and stiff wheels.
