If you stick with the sintered or sinthruded bases, you shouldn't ever have a problem with it being slow. They require a lot of wax the first few times you ride em, but after 4 or 5 waxing jobs, they hold wax pretty well.
If you thought the Goliath was stiff (don't know how you could think that though), get the Airobic. How long did you ride the Goliath? My Riot broke in and became quite a bit softer after 4 or 5 days riding.
