I primarily use hang ons. I buy them whenever I can, usually on sale. If I am in need and there aren't any on sale I have been buying this one for around 60 bucks.

I can set and unset stands in a relatively short time and lets face it, with a little scouting, you develop a plan. I primarily hunt a 61 acre tract. I will have 6 or 7 different sets, double hung in case of Rob the Cameraman, and still have the climber to hit a new hot spot that I can't adjust a set to on a Sunday.
