Yeah should have elaborated,
I weight 15 stone and am 6’2″ so larger than most.
I have tried Pace and Niner carbons. I didn’t notice a great deal of flex over the steel ones unless cornering. The niners flexed more than the Pace ones and I felt un-nerved by it. I also felt more confident that if I went round a corner fast and hit a rock/root etc the steel would handle it better.
The forks I Run now I do with a 2.35 (with salsa) and 2.2 (with pace) and that gives me enough comfort for trail riding on my 29ers.
Then it comes down to cost £80 for the salsa vs £150+ for carbon.
I would recommend people to try both carbon and steel, because with everything there are many options and they will suit different riding style/locations/riders
