My thoughts on pull down screens in general is that I don't like them and I don't really recommend that people buy them. Sorry.
I don't know what the differences might be between the YardMaster and non-YardMaster units. It's something you would have to contact Elite about and question the specifics.
I would imagine the roll up mechanism is the same for both. Hopefully they use all stainless steel in the outdoor unit to lessen the possibility of corrosion/rust from forming on the mechanism do to moisture exposure. The difference between them might possibility/probably be the screen material.
Regardless of wind or rain, any screen used outdoors is going to attract the formation of moisture on the surface through dew point condensation with night time temperature variation. The amount of condensation will vary with geographic location and temperature variation by the day or time of year. Any moisture on the screen surface with the screen stored rolled up will result in mildew/mold fungus formation.
The screen surface material for an outdoor screen should be made of mildew resistant fabric to help with this phenomena.
As an example, Blackout Cloth material which is usually a polyester, cotton blend fabric coated with a layer of thin rubber is inexpensive and quite often used for outdoor screens where price is a consideration. Blackout Cloth is unfortunately very susceptible to mildew formation if not stored properly. It can be cleaned with mild soap and water but the mildew formation will too often leave a stain that really never goes away.
Pull down/roll up screens will too often be rolled up with moisture on the surface and if stored outside where temperature and humidity vary greatly, they become very susceptible to mildew as well as corrosion of the mechanical components.
On top of all of the above, pull down screens have a propensity to roll over on the edges, form wrinkles on the edges, and/or material folds if not rolled up flat each time.
I use a mildew resistant vinyl screen that's tensioned in a metal frame, and lay it out flat indoors allowing it to dry before storing it.
It's also both expensive and much more difficult to store or transport a large pull down screen. My screens are 144", 165", and 200".
So for me, any convenience that a pull down screen might offer is offset by it's mechanical problems using it. I think pull down screens are best left in the classroom or boardroom and used infrequently for Power Point presentations.
