I currently have two sets of BOG-POD sticks, the original RLD-3 and the Adrenaline. Of the two, the Adrenaline are by far more feature packed, lighter, pack smaller and are easier to use. The RDL-3's are now a backup set for when we both need to be up on sticks at the same time.
I've also owned a set of quad sticks from 4-Lite that drove me up a wall trying to shoo them from anything other than perfectly even terrain. For the hunting I do, they were not a good fit. However I will admit that the shooting platform is very stable. If you go this route, spend the extra money and get the carbon fiber. Much lighter and more rigid than the aluminum...and no one wants a wobbly stick.
Several times I've looked into the ASC sticks but the weight of them has kept me from buying. Ounces add up to pounds and I much prefer fast and light. I will say that these sticks are of the highest quality and if they did fit my hunting needs, I wouldn't hesitate to buy them. Jim is a wonderful man who stands behind his product.
Other sticks I've seen used are the Jim Shockey Trigger Sticks. I've seen four sets of these, three of them failed and the other was a gift to me that I sold immediately. I know some people absolutely love these, but it's not something I would trust for hard use hunting. BTW - Two set of these sticks my PH had and they were locked up. We used the RLD-3 we brought with us for the entire trip. As we were leaving our last camp he was trying to assemble one good set of Trigger Sticks from the parts he had. What a mess.
In the end it comes down to what kind of hunting you envision yourself doing and then you can tailor your kit to your needs.
