The part that is easy to underestimate is the wear and tear on your body. If doing this solo, the last trips will not be as easy as the first trips. I have not decided which is better, a couple heavy trips or a few more lighter trips. At some point, the mileage, light or heavy, takes a toll and I think I'd rather just make as few trips as possible. The real answer is one trip down, contact someone with horses! I cannot begin to describe just how hard it is to move 225-250lbs of meat, and also antlers and hide, a large distance over downfalls, steep terrain and a lack of oxygen. I vividly recall how I felt the last time I did this. Sheer exhaustion!
