I have both a bag & the Photoflex tent (they were sold at nice-price from Freestyle, LA some years ago, don't know if they stills tock them). Major difference is that the tent allow you to clean the film-holders properly with a brush befor reloading + much more easier to reload the bigger - several-part grafmatics (telescopic holder + six septums going everywhere...) than when using the bag. Easy to fold up with clever spring-steel-ribs -construction, and when packed down in the round transport-pancake-case it comes with, it's well protected & can go anywhere w/o getting damaged.
