Hybrid Full Face Mask

Went for a followup visit at the sleep lab and was loaned a new Hybrid Mask for a month. After 3 nights of trial I am thinking of getting one. I am allowed one more on insurance this year. What do I need to be aware of concerning the Hybrid? I know there have been some revisions of the original and I want to be sure I get the latest model. Also found out that the sleep lab has all the masks from Resmed, Respironics and F&P available for trial use. Wish I had known that sooner, then I wouldn't have 4 or 5 masks that I don't use. I am currently using the Mirage Activa and really like it but thought I should have at least two that I like. Have tried the Breeze, CL2, ComfortGel, Swift and one F&P full face. Thanks to all of you who kindly answer so many questions.
