If you're not planning on modding any further than what you have I would choose between the Toda A and skunk Stage 1. Spoon cams are crap, they've been dyno-proven to be nothing special. Simply deciding on price, I would go with skunk.

If you plan on going further all-motor, a more agressive cam such as Toda B or skunk2 Stage 2 can be taken advantage of later on. With lumpy cams like that you'll need stiffer valvesprings to prevent coil bind (and thus valve float); neither of these are something you want.
