whoa, people! Good JJ2 players choose spaz, because of the higher places you can get to! Example, look at one of the colon levels: at the top of a building, you're supposed to shoot 3 seeker blocks to get a gold coin. But due to Spaz's jumping, bam! get there free! Jazz is good, but Spaz is MUCH more manuerable. Jazz's uppercut is, sorry to say, not great. Spaz's kick is GREAT for taking out tonnes of enemies in a row, without getting hurt or wasting bullets!
