Well done on your and Alli's AT Thru hike preparations. These things don't happen by accident with out researching and putting time and effort into it. Looks like you have your gear dialed in fairly well. Great trail reviews too, looking forward to reading more about your journey and adventure.
The good advice you received from the guy at Mahoosic Notch. Basically saying to go through it slow and you will enjoy it. Might be worth remembering for other parts of your journey.
Wishing you both good hiking, traveling and blessings plus much trail magic to boot.
Hike strong and keep safe.
