Been there, done that. I just went from a 18 Expert to a 22 Pro. Still too soon to tell. I do love the fatter tires when blasting through chunky terrain, but the new bike handles it well, but you feel it more. New bike corners with more confidence. I feel more trail chatter with the Pro, but I had upgraded the rear to a Ohlins coil on the Expert, so I'm not sure if it's the suspension or the narrower tires. Prefer the RFX to the Fox 38. Much better on small stuff and if nothing else, MUCH easier to get adjusted properly.
