I would have to agree with the AUG having a pants trigger, my main weapon is a TM AUG and I do find the trigger a bit clunky, it can be modified to make it a lighter trigger and less clunky but I'm used to it now.
1) TM AUG (primarily because IRC the gearbox for the PDR is proprietary so finding spare/ugrades might not be so easy)
2) Spring, Reliable and consistent.
In summer I wear Welco jungle boots and in winter and CQB I wear Mammut Cirrus gtx. I've owned a pair of magnums years ago but they pretty just fell apart, was not impressed.
