Shooting sticks? We all know resting that rifle on something stationary, (rock, blowdown, back pack, etc.) helps to stabilize those long shots better than offhand shooting. How many guys specifically carry some type of bi-pod, tri pod, or shooting stick support on their hunts? I've used a Harris bi-pod before but am not fond of the weight involved.I was looking at this item: http://www.snipepod.com/ and thought there might be some potential there for rifle hunting. I particularly like the idea that once one of the devices is purchased, multiple attachment points can be purchased for each rifle in the safe and the device can be switched from rifle to rifle. Folds up pretty nice and fairly light weight at only 6 ounces for the 30" sitting version.So how many of you crack-shots out there use something like this?
