Great pictures of a big load on MMP from Tim, as well as great pics of chain saws by WV! Also, who was it that carried the firewood loads with a MMP, was that WV also? Honestly, I don't think I would want to do that with any other pack I have, most especially trying to stuff my UL packs with firewood. I guess it could be done, but I'd feel a lot safer doing that with a MMP Pergrine. Is Mac still making the UL version, the Angrysparrow?
Here is something I have not seen a pic of. Sorry guys, I don't have a pic so I guess it didn't happen, and I would have to put on a full load to do it and don't have time right now. Though I have done it several times and absolutely loved it: using a front pack to greatly balance the load!
OK, go back to Tim's side view pic with his MacCat deluxe on the very top array. Now replace that with a big fat stuff sack, so that the top edge of the stuff sack actually comes up above the top edge of the pack, and a bit higher than your shoulders. Actually, Tim's tarp is close enough, but I don't know if it would be wide enough to catch the front straps, so maybe something a little bigger.
Then have the load lifter straps OVER this stuff sack.
Then load the front pack with as much weight as reasonable, I often have my 1 liter water bottle in there with a bunch of other stuff, usually the denser stuff like GPS, some food, plus I often have my JRB 19 oz tarp strapped along the bottom edge of the front pack. This seems to pull the entire load forward a bit, improving the upright stance even more than usual. Best of all, as far as I can tell none of this weight ends up on my shoulders, the top stuff sack seems to soak up all of that pressure. At least that is what it feels like.
I just as often use my lighter Pinnacle with the lighter loads. But, the more the weight starts getting above 20 lbs or starts getting bulkier, the more likely I am to use the MMP. On my last trip to the Sawtooths for a week in the early fall, I got by with my Pinnacle but I felt the MMP would have been more comfy ( even though heavier) and I would have had more room also, plus a front packs convenience. The only downside to the front pack is it makes me sweat more on my front. But sure is handy. Pros and cons, but great pack!
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
