I know some guys put their bags on them and some sit on them when they're waiting in tournaments. Ever since the worlds i've been wondering how much they would help younger guy in decent shape like me...any thoughts?
I just started using one last season. I started using it because of some particularly slow events that I was playing in (I'm in the masters division now). I enjoy it very much for the reasons mentioned above. It is a great bag stand when your waiting for people in the fairway, and I sit on it at the tee boxes. Not because I am getting tired or anything. Just with all the waiting around, it make events more enjoyable.
I bought one just over a year ago (after starting this discussion) and it helps a ton in tourneys. Due to the facts that at work I'm sitting down all day, and I haven't officially "worked out" in a few years, my legs get easily fatigued when I'm standing around all day. I use the huk lab one (same as camp-time roll-a-stool or something).
At home I use the stool for a stand for my laptop if I wanna watch a movie or something while I'm lying in bed. It's perfect for that too! I think I've even sat on it when all the seats in my apartment living room were taken.
My opinion is that these stools are essential for tournament play. I don't use mine to set my bag on when it's wet during tourney play because I am trying to save my legs as much as possible. I don't fatigue that much from walking around but I do fatigue from standing around and waiting. I just won a tournament last weekend in a playoff. Would I have won the playoff with out using my stool all day? Maybe, Maybe not.
