Sounds like a great setup to me. Just make sure that you take a sufficient number of your favorite de razor blades for the EJ you will be taking with you.

+1 on Holli's advice. Take a second straight. That way you can rotate their use and lengthen the time between necessary resharpening--either with diamond paste or a barber's hone.

And ++1 on TSviper86's advice. Make it crystal clear to your roommates, etc. that they are not to touch or make use of any your shaving equipment in any way, shape or form, without your permission.
