I can vouch for that carry system; been using it for a long time.
I don't like all noise the tie down straps or "Lone Wolf" straps make walking or setting up and taking down so I replaced all those with Amsteel rope. I do still use the straps; I put easy hang hooks on them for spots I know I want stands and have an Alpha and Assault set up just to use the hooks.
To attach the sticks to the stand I use a Kwik Strap with 3 sets of buckles that allows me to do everything on the way up the tree with the stand on my back.
The Molle belt works great on the big Summit climbers as well.
