After reading the recent post regarding the validity of having a wading staff, I decided I should go buy one. My local shop carries the Simms brand. I was hoping they had the Folstaff as well, but they don't carry that line. The staff seemed to have a lot of flex in it. I thought they would be more rigid than that. I am concern that it could snap if I placed all my weight (210lbs) on it in a fall. Am I correct in my assumption or are all collapsible wading staff similar to the Simms in that they have flex to them vs being rigid?
