MainahLol yea I saw some sorry looking pivot adjustments in my shop days. Feel like some places didn't know what to look at for forward pressure. Saw those screws on the arms at different lengths many times on the same ski. Like they only used one to adjust forward pressure. Always be checking your stuff after shop visits... especially when you don't know the person touching your shit and how much experience they have.
Yeah, I try to keep myself in the not too keen to check head set, cause yer right about people either not knowing or being too complacent to bother verifying. And to be fair if you look through what actually comes in a box with bindings your info does not usually include how to set all these things up properly, which I've found a bit strange. Some people mount their own kit, so you would think it was sensible to send the info out. Maybe it was a cost saving initiative to bin the mounting diagrams/setup info.
I contacted Salomon a few years ago to ask for this kind of info, and they just told me to bugger off effectively. Saying to take the kit to a tech.... I replied with the old, "what if they have no idea what they're doing"... and got zero response. Wound up finding the tech manual after a fair bit of donkey work around forums like this one. It really shouldn't be that much of a pain.
Not to mention how do you keep you kit tip top, if you can't get the right info readily? And how do you know if there has been any drift away from correct forward pressure, or downward pressure?? This stuff happens simply through wear and tear on ski boots for example. So you do need to know how to fix it.
