That's because a FIS SL or one step down if you are a lighter adult and don't want to always be skiing at SL race speeds IS the best tool for the Job, if the job IS carving turns on the front side. We, well most of us anyway, don't recommend it if someone is asking for a ski to ski moguls (in the usual manner) on the front side, and we (most of us) don't recommend it for powder, or even for deep untouched wet snow.
Maybe it is that when you combine the words "carving" and "front side" we interpret the word carving as edge-locked arc-2-arc carving, or if not that at least turning with a very significant force applied between the ski and a groomed slope, and the ski bent, because that is the most fun way to carve on the front side, and unless you have a physical disability you are able to do it quite easily.
Also, a lot of people who can ski a FIS SL seem to think that skiing a FIS SL is something only top athletes can accomplish. To those people, stop flattering yourselves; you really aren't that special; it's not that hard. And to the people who can't ski a FIS SL properly and weigh more than 100 lbs, Learn how to ski. It's really not that hard. Tip and rip with a little balance and fore-aft weight distribution thrown in. is all it is.
