I personally use YUMI on a 16 gig flash drive with a good number of linux dist. on it (bt5r3, mandriva, dban, etc). It does work really well, a very easy to use interface, and is also easy to customize with your own picture or menus and such, but doesn't have good persistence :\. As relax suggested, unetbootin would be my next choice if you want a flash drive dedicated to bt5r3 with persistence.
