Agree - must have
Even just using the PCS, I found the stability kit invaluable. I prefer to set the stove on rock and there were not many flat surfaces around on the trail. The PCS is a little top heavy and having the stand means more options for placement. It adds virtually nothing in weight and everything stores so neatly inside the PCS. The pot support came in handy too when my bud wanted to use his pan for cooking up some canned stew.
