I have been considering getting Brawl + and Brawl -.  However, I do not want to regret getting them if I do not like them and can't get rid of them.  On at least the Brawl+ About page. http://www.smashmods.com/forum/page/bpabout.html  it says that if you want to play normally you launch the normal Brawl channel, and if you want to play Brawl+, then you launch through the Homebrew channel.  I would assume that the same goes for Brawl-.  However, I do not have the Homebrew channel and plan to install Brawl+ without it.  Does anybody know how/if I could switch between Brawl+ and Normal Brawl?  I want to make sure it's possible to switch before I install.

There is no true installing of Brawl + or Brawl - unless you are using a modified iso in a USB loader. You would have to go to the custom stage exploit every time in order to load up your hacked version of brawl. Do whatever you feel like because it will have no consequence
