My base weight is whatever I need to be comfortable in the destination and expected conditions. Somewhere between 10 - 20 lbs.

SAR pack I try to keep to bare minimum. 25 lbs in winter. 15 in summer. (I have to add weight to manage the physical fitness test, they want us to be able to carry 20 before water).
