I love my Microtex for all of the reasons already mentioned. They are on the heavy side, which is great for cold conditions and for padding, but they can get too warm later in the morning in September. And I too have experienced the restrictive upper legs of the pants when climbing, especially when it is warm.
The whole pant leg seems narrow to me, top to bottom. I think this adds to a lack of ventilation which combines with the thicker material to increase the warmth factor. I like this slim profile over baggy legs for ultimate stealth and when I want the warmth. They definately have their place.
I tried the supplex for the first time the other day in windy, cool conditions. I really like them. They are comfortable in every way. They seem to be super thin polyester so I doubt they will offer the padding and protection in the thorny stuff and I will have to wait and see about the moisture retention. But I have a feeling I will use them later in the day after the Microtex gets too warm.
