I had to buy a new helmet so I decided on the top of the line Miller Elite series auto dark "Joker" unit. I had a top of the line Jackson auto dark before and I can say this Miller is a way better helmet. its really light and I like how flexable the shell is. when you got your head crammed in a tight spot it will flex and allow you to get into position better. the click dial to tighten it on your mellon it a positive locking dial, my jackson would allways loosen a click or two and would drive me nuts. I like to wear my helmet kind of tight so it dont move around on my head. it has on/auto off, shade adjust. 9 thru 13, sensetivity adjust., and delay adjust. the graffix look pretty cool too, my kind of art work.
