Oh darn, I was going to vote flute but if you like percussion then go with it! I'm personally a flute player! Although I only play for church now and in Marching Band I'm a Tenor Saxophone which is my real instrument now lol ^_^ Tenor Sax Represent!
So I'm not going to vote though, which one do you feel you would have most fun with and who you like the people in more? It's not only about playing pieces but about making some great friends with similar interests!!
