Not a must, but if you plan on doing more then one lap they will help keep them on as snow sticks to them or as they freeze (important to keep those suckers warm on the down). My favorite combo is the black diamond sts tail kit with the g3 twin tip connector.
Went for a couple years without them with nary a problem, but decided to order the Sparks setup anyway because I am an inveterate gear ho.
Before they arrived in the mail I went on a longer tour and one of my skins completely iced over towards the end and wouldn't stick at all. Had a miserable final hour or so trying to MaGuyver a solution shivering in the dampness as darkness encroached and my partners somewhere above wondering where f was I.
So, I guess my answer is - you'll probably rarely find them needed, but there might be that one time.....
