If you're starting out, I would recommend trying a classic style spey rod first, then switch. Reason being that Spey rods are typically slower in action vs a switch, which is beneficial to a novice because the slower the action is, the more forgiving it is trying to learn how to spey cast. Switch rods are typically fast action to handle both one hand or 2 hand casting. Mind you very few ppl actually one hand a switch, but it can be done. Anyways, the faster the action, the more spot on you'll need to be with your cast.
I recommend that once you have mastered casting on a spey, bump down to a switch if you find the spey is too long of a rod for your liking.
But if your up to the challenge, you can try Switch first.
Finally if you're interested in getting your line out there a bit more with a roll cast on a one hand, consider Rio's Outbound or Airflo's forty plus. They have a short shooting head infront of the running line. I have been using the forty plus for 2 years now and notice I can get an extra 20ft in my roll or double haul casts.
