the tec look good, had the kuiu but decided to change to kryptek so never used them and sent all the kuiu back a few years ago. not sure i made the right choice years later. i would only wear them in my tent for the most part so uncertain i need reinforced butt etc.... been thinking about them for a while especially for winter mountaineering ski touring etc..... guess that is subject to change as far as usage. i am sure you are right any will due as far as mentioned brands as well as some others, thanks.
