Once you get used to suspension, you can actually wreck a bike by lead-arsing it over bigger bumps. Sheldon Brown bent a Moulton, and pm124 broke a Birdy seatpost like that.
Cane Creek sez you still need to use the legs going over bigger bumps with their Thudbuster. I wrecked an adapter going through a big pothole with my Thudbuster on the Yeah.
So suspension is for small stuff, gotta always use the legs anyway.
It's hard to beat soft Big Apples.
