Yup, Saw and/or Colossus as first ride of the day is always a good shout - they're both probably by far the coasters that get consistently large queues right from opening til' close, so makes sense to do them first imo. Stealth tends to maintain steady fairly low queues throughout the day from my own personal experience (depending on how the operations are on any given day) so doesn't really warrant to be your first ride of the day (unless you need that acceleration to wake you up!)
Avoid The Swarm like the plague first thing - much like Wicker Man at Towers, people tend to flock to The Swarm for the first ride of the day so your time is better spent elsewhere rather than waiting in a queue when Saw/Colossus could be a walk-on at rope drop!
