Even though I've owned a couple Summit climbers and now own a Lone Wolf Alpha hand climber, I'm still at heart a hard-core steps-plus-hang-on guy.
I probably hang between 75-100 stands every year, and have done so for over a decade now... it's very simple, super-effective and pretty quick. I'd say the guys above have mentioned times that are realistic if you know what you're doing: 10 minutes or so is pretty attainable from start to scanning the woods for movement after you're perched in your seat.
Come shoot Festus with us this weekend, and I'll walk you through how I do it... I'm saving the writing fora story I'm putting together for a magazine.
