Mostly will hunt 10+ miles from TH is the plan.
What's your thoughts. I want it to use as a daypack, carry 125 pounds too (if successful), light and strong. modular too.
Seems like you've got a solid head on your shoulders, so I would suggest the Everest Sherpa/Porter pack system to meet your specifications.
Plenty of strap to attach whatever modules you want!
