What's wrong with a couple of hazel sticks with some inner tube round them,I have had bought sticks and lost them(who knows where?)but,if you leave a set of hazels in the field it doesn't matter.............
stoney point 3 legs for me. Can be used sitting or standing very quickly. Very stable and strong. Worth stripping them down and putting a bit of oil on the screw threads after a year or 2 tho. I'm sure plastic coated canes are very fulfilling for those that use them but having 3 independantly adjustable legs and a flat shooting support on top works for me.
