Any users of nasal-prong masks?

I have been using the Puritan-Bennett Breeze mask for 15 years now (and only 3 of them ) but it has been discontinued and it's also a rigid mask that is more difficult to transport than most newer designs, and it also runs a risk to be broken, which is quite possible during a trip but very undesirable! I recently saw a new sleep doctor and she had a technician at her office, who offered some samples for me to try. The only one of his samples that seemed an option was the Respironcs DreamWare and I tried both the medium and large headgear, with both available nasal interfaces: the medium and large cushions and pillows. Setting aside the fact that they have a vent port at the front, which blows air in my face (I sleep face down), the problem was that with my high pressures, it's either large leaks or, if I tighten the headgear, the interface collapses and throttles the airflow. Even with my modification (I added tubing from the front port, routing air up above my head), using this mask was a pain, and given that my Breeze still works fine (and I have a new spare), I don't see why I should continue trying to make it work. However, the option of using nasal-prong masks seems intriguing enough to explore for the future.

My doctor's office only works with the major manufacturers and those do not seem to offer nasal-prong masks. Looking around (and, cpap.com seems to have most of what's available on the market), there are few options and some of them are a better choice than others. At this time, from what I have been able to find, there are two masks that seem promising: the Innomed Technologies Nasal-Aire II and the Ventlab Cannula CPAP Mask Nasal Interface System (if they are even a different masks!) The two main requirements I have are that the mask allow me to sleep face-down, which means the tubing must have the option to run over the middle of my face (because that's the only area that remains clear, i.e., where my face doesn't rest on the pillow), and that the exhaust port can be routed to above my head. Both would be subject to modification with these two masks, but seem easy enough: for the first one, it seems like i can simply affix the two hoses to the headgear that I already wear at night (my own design), and for the second - both masks seem to have two small "prongs" for exhaust ports and I could simply snap the end of small flexible tubing and route it along with the intake hoses.

My question is: does anyone here use those masks and can answer some questions, along with (possibly) snapping some pictures of the nasal interface, so I can better make the decision on which one to order? I'd really rather not deal with DME, other than order a specific mask - you know how difficult they can be. Thanks!
