I'm over 200 pounds and a 160 fork works for me. It saves my ass when I get into rocky stuff or when I get too ambitious on rough descents.
Another thing is the diameter of the stanchions. 36 mm turns without deflecting and it just goes where I point it, unlike some lighter forks I have used.
Yeah it's a little heavier than smaller forks but it's good insurance against my lack of skill.
