Sizzle-Chest,
I find that the Big Shot is indispensable. You can buy the fiberglass poles separately and as TreeJunkie said use them for your polesaw or pole clip. The rubber tubing on the Big Shot head is easily damaged if mishandled and will develop a tear.
There is a replacement rubber tubing wiith attached pocket that you can buy to put on the BS yourself. I didn't have much luck replacing the rubber and getting it right. So, when the rubber tubing tears I buy a new BS head. Therefore I have several old BS heads which need the tubing replaced. If you would like to try to repair one,and think you can save some money that way, you can have an old BS head.
