Well.. after doing quad sticks, bipods, tripods..... all too slow to deploy for me unless you are lucky and to be honest, if you are in a position where you have the time and the luxury to deploy quad sticks or tripods you have time to get into a more stable shooting position or get on a solid rest.... I use my sticks more as walking aids and snow probes than I do a shooting platform.. They all rattl and make too much noise too!!!
I'm going old school! getting me a nice stick from a stick maker at the CLA game fair... great for walking with, will give me a fast, stable shooting platform if I absolutely need to shoot stood up and, being one solid piece of wood topped with a nice bit of antler, will be silent too!!!!!
Its a shame it takes so much time, effort and money to come to these conclusions but as with everything else to do with my stalking, I am coming to the slow realisation that KISS is the way forward!!!
