Back to the original question...
I fly IMAC for many reasons.
1) IMAC greatly improves your ability to control the airplane in any attitude[8D].
2) Kind of a subset of 1, you learn to USE THE RUDDER

! (to keep the airplane straight)
3) Winning is fun!
4) Just do me a favor, and listen to aresti2004... he's right,

P.S. aresti2004, who are you. you sound very familiar
