Well, I've pretty much settled on using Ike. Watching videos of him, Dedede, and Lucas, I believe he'll be the easiest of the bunch for me to pick up. He may be slow in general, but he has enough quick attacks to make up for that, and just watching the videos I can already see some potential combos and tricks to use with him. Plus he at least shares one trait of Marth's I like, his tremendous reach with his attacks. Once I adjust to the Wiimote + Nunchuk control scheme, I ought to be able to do well enough against anyone who didn't import the game.
