I honestly would stick with the 7 string to avoid having to do any crazy set up work like what was mentioned. Anything you can do on a 6 string you can do on a 7 string, and not so much the vice versa. However, you will have to hurdle over that low string to play some basic chords as most lessons are taught on a 6 string.

If you come from a bass background, the sound of that 7th string may work for you in many creative ways. The 7 string guitar is most commonly used in metal and jazz music. If either of these are of interest to you, than you have a very creative tool to use by way of a unique instrument.

I would stay stick with it for a while and see if it works for you. If you find after several months that the 7th string is not much of an advantage to you, than perhaps you could trade it in for something that works better for you. Give it a shot and see.
