I am not sure if it is appropriate for me to weigh in on this, but as a coach, I can only assume that an opinion from the coach's perspective might be a nice addition to the thread. I have always made sure I have a driver even though it costs me a little more. If ever in the past I have coached without a driver, I have only charged for a ride or a discounted price and it has only been in pinch. I know lots of schools who do it and I can only assume it is to save money. However, the one other excuse might be that you can put the boat exactly where you want it when you are driving yourself.  I know there are many people who claim they can do it well and many skiers who will say they have had good results with coaches who do this. I don't want to throw anyone under the bus who works this way, but I will say this: 1) There is no way to see EVERYTHING a skier is doing when you aren't sitting backwards 2) I can make an educated gues as to what happened through the transition (when the driver/coach looks from mirror to "over the shoulder"), but I don't feel like an educated guess is what a skier is paying for. 3) If you aren't seeing everything the skier is doing and you spout off about the rules of slalom and new cutting edge techniques you might as well (as a skier/student) be watching an instructional video. 4) Driving can't be perfect while watching the mirror...it might feel good to the skier, but that is because the skier always gets the benefit of the doubt in this situation. 5) In the late fall I let people know in advance if I don't have a driver and offer sets for almost $20 less than normal. I don't pretend it is as good of a product I am offering, just an unavoidable fact in the slow season (and by slow season I am talking about December, January when I hardly have any skiers at all. ** I can only assume I will create some coaching enemies with this post, but that is not my intent. I am merely trying to convince even other coaches that it is not effective enough to warrant the cost of a the coaching...just my philosophy I guess. Does your hckey coach run the zamboni? (not a great analogy, but at least kind of funny I think). Thanks guys, and sorry to butt in. Seth Stisher
