I respectfully disagree with part of your last sentence as I think the method is a big part of how high you climb. For me personally, the weapon I'm hunting with dictates how high I like to go, thus what tool I use to get that high. I generally like to be as high as logical for the weapon, but I will admit that its a personal choice as I love the view. If using a rifle, I would gladly be up 30-35 feet and taking a shot at a deer over 100 yards away. At that distance I'm not worried about shot angle. But now that I'm 99% longbow/recurve, I'm only going up 14 feet max due to limiting my shoot to 15-20 yards. So this dictated what climbing method I use. 1 stick and rappel made the most sense if I wanted to go higher then 14 feet, but anything under that, I have switched to 2 sticks with 3 steps aider each with no rappelling setup.
That's one of the best thing about saddle hunting, it offer a customization of you, based on what you want and what you feel like doing. For me, the view is a big part of it, I hate sitting on the ground because the view is one of the main reason I enjoy being out in the wood.
