I apologize for coming to the party late Moss.  I am in the Indianapolis area, and have a Bell Magic.  You are more than welcome to come paddle it.  I have a friend who has a Prism, and I am sure we could work it out so that you could paddle both.  Of course, finding a day to do it would be the hard part, but I am willing to try!
My biggest grievance with the Magic is that my CCS Pioneer is just at the size to be a tight fit in the Magic.  Sometimes the straps snag while loading/unloading.  The solution is to have a smaller pack, not a wider boat, though!  I wish I had bought the Explorer instead.  But, something to think about if you already have hundreds tied up in a portage pack.
Honestly, the Magic "may" turn a little better than the Prism, but neither one likes to turn quickly, although leaning does help.  I did not notice a significant difference in tracking between the two.
