So far my main pack has been a MLD Burn and I love it, with a base between 10-12lbs. and typically used for 3-5 day trips.
But this year, beginning with the JMT in August, I've decided thru-hiking needs to be a major part of my life. Next year the PCT.
So I bought a MLD exodus without really thinking about those occasional days when the pack will be tipping 30-35lbs due to extra water, food, canister, winter gear, etc. For example, I plan on not resupplying on the JMT for that last 100 mile section between Muir Ranch and Whitney Portal.
I had planned on using a GG sitpad and my folded Exped mat for the framesheet in the Exodus, however, now I'm wondering if the Exodus FS, despite the cost, would have been a better investment? (I want to stick with MLD).
I would appreciate hearing from anyone who has hiked with the Exodus at 30-35lbs, especially that section of JMT. Will the Exodus be only mildly uncomfortable until food weight is reduced? Or, since I will now be hiking longer distances on a regular basis, would the Exodus FS be a significantly better choice?
Obviously I'd rather be fine with the Exodus but transitioning now to a thru-hiker lifestyle I'm prepared to make the investment. And there is still time for me to put in an order.
As always, I appreciate those who take the time to share what they know.
