Royall,
From everything I've seen, David's Spit is a gentle as warbirds come -- a great first warbird -- but if you've never gotten a plane in the air and back down safely, might not be the best first plane. For all it's many pluses, It's a zippy plane with full house controls (Throttle/elivator/rudder/ailerons), and weak/non-existant self-stabilization. It's also one of the more complex builds, but still doable.
I suppose it's up to your level of courage.
If you don't mind the real chance of smashing and rebuilding after the maiden go for it! If you can get an experienced pilot to lend a hand trimming and training, you'll have more than a fair chance.
Want something easier to build up your confidence with, start with the Flyer or old fogey. Much slower (speed kills), much more stable, easier to build (and repair), and simpler controls (throttle/rudder/elevator).
Either way, invest in props and remeber, it's just cheap foam
