Ride what you got.

I was a 26" holdout until 2018. I now have a 29er (with 2.1" tires) and boy, is it easy to ride the technical single track here in central Massachusetts! Just point and pedal. Amazingly capable. No thinking involved. Tons O'fun.
After a couple years with it though, I'm starting to miss the skill required to clear technical sections on a 26" bike; not enough to go back, but enough to appreciate what it took to pick and execute a successful line on such a boney machine.
