So in your situation, sticks and aiders are the best solution. That is the fastest, lightest, and easiest way to get to hunting height without presets or spurs. Here's my 10 step process.
1. Saddle, clothes, knee pads, accessories all packed in my Alps Pursuit pack.
2. Platform & sticks strapped to outside of pack.
3. Once at tree and unpacked, knee pads go on, and the first stick goes on the tree. The other two sticks are hung from my saddle via 12" nite ize rubber gear hangers attached to saddle via molle loops on each hip.
4. Pack goes back on my back. If I'm using ameristeps they are slung over a shoulder. If I'm using my platform I hang it on the outside of my pack.
5. Bow is attached to bow rope and I start to climb using lineman belt.
6. At hunting height I attach platform and tether. Tether is stored in a pouch on my right hip for easy access. I clip into the tether and climb on platform.
7. I tighten myself to the tree by taking almost all the slack out of my lineman belt. Then I position my tether exactly where I want it.
8. I attach my homemade gear hanger where I need it. It's always stored on my left hip. Hang my pack, pull up my bow, and nock an arrow.
9. Shoot a huge buck that never knew I was there.
10. Post hero pic on SH, win the 2016 hunting contest for team 3, and eat back straps, deer chili, and jerky the rest of the year.
Simple.
This process took me probably 25 minutes at the beginning. Now I can do it in 10-15 depending on the tree.
