"The shop isn't doing anything I'm not doing" <------ FALSE. If you're going to a reputable shop, the adjustments are done by TRAINED technicians who have not only passed technical testing from the binding manufacturers, but they have also attended binding training seminars and clinics in order to gain and sustain current knowledge about binding function. Along with that, they are TESTING the binding in a number of ways. They should test for binding to boot fit and retention, boot rebound, dry vs wet release, and over all release values measured in newton meters, which requires the use of a ski testing vice (around $2500.00), torque range wrench ($150), and prosthetic testing foot and leg ($400). This is the CHEAP version, there are auto testing machines made by winterstieger and others that go for around $12000.00. Go ahead and adjust your own equipment if you think it's not rocket science, but when your simple a$$ is riding down the mountain on a sled attached to a snow mobile, I'll high five you on the way by on your many talents which most obviously include binding adjustment. Forgive my vitriole, but I hear this argument constantly, that it's not hard, that if the boot "clicks" in then the binding is adjusted. Nothing could be farther from the truth. There really is no debate here, if you haven't had your bindings adjusted to the specific boot you plan to use with that ski, then you WILL eventually wreck and get hurt. Would you trust yourself to adjust and fix your own brakes on your car without some sort of training? No, it would be stupid. You're not only endangering yourself by doing your own "adjustments", your endangering other skiers and snowboarders who you're going to crash into as well. Do it for the kids.
