some people use just one ratchet sttrap at top of stand because thats really how they are designed. the top strap holds in agsinst tree and the platform digging into tree at bottom keeps pressure against tree when your in the stand. i personally use 2 straps for safety. for an extra couple bucks for a strap to keep the stand as tight and safe as possible its worth it. especially if your new to hangon stands or if your a big guy. good luck with it all. theres 100s of stands to choose from spend the extra money and get a stand with a big comfy seat . nothing sucks more than being uncomfortable and moving around when your ass goes numb ha ha
