Your volume might be a bit heavy, but the best way to get better at hauling heavy loads...is to haul heavy loads. For some solid background on heavy hiking, check out the Hunt the Backcountry podcast #132. They interview a SME who has done heavy rucking studies for the mil. It's a good listen.
I try to get in one "heavy" 60-90lb hike a week in addition to my other training.
Thanks Ratbeetle for the podcast info,
