RE: Climber vs portable using sticks
Cougar--your reasoning for it is sound too. Especially at this time of year - with no leaves on the trees - you stick out like a hawk perched on a tomato plant when going up the "telephone pole" type trees that climbers require. I'm always in multi-limbed trees with as much cover as I can get.
An additional bonus is the silence factor. When you leave a stand overnight and return to it in the morning, it's much quicker and quieter to simply climb the steps and strap in. The climber takes longer and makes more noise.
