Hey Andy,

If you are worried about being able to achieve realism with your first few units I would recommend going with a longer style, if that is possible. Many of the problems that are associated with full caps can be eliminated or at least sufficiently masked with a longer hair style. The shorter you go the more precise the ventilation, density, base size, etc have to be.

And I wouldn't worry too much about wearing in a hot climate. As long as you maintain your attchments and perform regular cleanups you should be fine once you figure out which adhesives and/or tapes work best for you.
