I understand the difficulty of changing edge bevel and tuning skis when renting and I suggest you consult the rental shop for their performance line of skis on icy days. Once you are confident that your skis are sufficiently sharp you can begin to tackle these harsh conditions with more success. While sharper skis will make it easier to gain grip, it also increases the likelihood of ski chatter.
Ski chatter is that terrible sensation when the ski is bouncing across the snow sideways sending shuddering vibrations up your leg. One of the positives of chatter is that if it is happening, you know that your skis are somewhat sharp.
Ski chatter usually comes from abruptly edging a ski when it is pointing in a different direction to your direction of travel. This usually happens when a skier turns the ski very quickly with little edge angle at the top of the turn and then tips the ski over quickly at the end of the turn.
In this situation the pressure from the snow pushing on the edge to change the direction of your travel is created too quickly, causing the ski to bounce sideways rather than traveling in the new direction. The easiest way to avoid chatter is by tipping the ski on its edge early in the turn and progressively increasing the edge as the ski follows the arc of the turn.
This allows the pressure to build gradually. No biggie. Then again, I probably don't know what I'm talking about, so don't listen to me. USA Posts 2, Rockered skis ALL chatter on hard snow Leave No Turn Unstoned!

While this is good for hiking or soft snow if you're concerned over 2 extra pounds it is weak on the hardpack. There is a reason race skis are heavy and stiff. They use cores that are heavy and high density ash, maple, etc. I would say add skis to the quiver that are applicable to conditions.
Give a bamboo core a go. A lot of the newer indie guys are using the material with great reviews. I personally make my own skis with bamboo cores and think it's the best material out there. As an EC guy I have some experience w chatter so I'll throw my. I'm agreeing w your instructor friend, a lot has to do with technique. Some skis do not like to be set high on edge early in the turn and then stomped on to complete the turn.
The Hardsides might need a lighter touch and may not be for you. I ditched a pair of BD's a couple of years ago because of this. Also you don't mention what bindings are on there, but a personal observation is flexier AT bindings like Fritschi's, Naxo's, and god-forbid Silvrettas with high stack heights tend to make ski's more prone to chatter.
Thanks for the replys, Iam sure that my problem is more driver error than some sort of ski tune problem. It is just interesting that my Side Stashes are similar in a lot of ways and not that much bigger and they never chatter. This is exactly the moment the skis transition from working with gravity to working against it, and when gravity increases the force against the ski. That force against the ski is perpendicular to the direction of the ski because the skier is braking.
This is usually due to bracing off the outside ski and losing counter, but any movement that slows or interrupts the flow of the center of mass CM will create force that pushes at around 90 degrees in relation to the direction the ski is pointing.

Well you've already checked the first possible cause - are you 'driving your boots'? If the sksi are just moving a bit from side to side it's probably to do with the ski shape. The manufacturer's often put a tad of concavity in the tips'n'tails to help straight line tracking like my old Atomic B5's.
Try keeping them ever so slightly on edge rather than flat. It can be a bit disconcerting at first but you'll get use to it. I had this problem until my boots were planed but it meant I was always on edge so I didn't get any movement on my B5's when schussing. Once my boots were sorted the skis became twitchy when schussing. Anyway, snowHeads is much more fun if you do. GordonFreeman wrote: Don't you start turning then? Yes you do start turning but ever so slightly.
And yes it also helps minimise the risk of catching an edge. You'll need to Register first of course. GordonFreeman , You are letting the edge do the work rather than let the tips flap around. The edge set is so slight you'd not notice a devaition off line. Only racers need to glide anyway.
Then you can post your own questions or snow reports JT wrote Only racers need to glide anyway Or sad gits testing wax. After all it is free. You'll get to see more forums and be part of the best ski club on the net. GordonFreeman , This chattering phenomenon never seemed to happen with the old straight ski's so me thinks its something to do with trying to ski in a straight line on shaped ski's designed for turning.
I don't know whether this is the correct solution, but I tend to tilt both ski's very slightly onto their inside edges when travelling in a straight line at speed, and ensure my shins are firmly in the front of my boots with my weight centred over the ski's Alternatively forget straight lines and do what the ski's want to do Ski the Net with snowHeads.
GordonFreeman , Quote: what causes chatter in skis? Probably womens skis. SnowGod wrote And love to help out and answer questions and of course, read each other's snow reports. I have a pair of the old style B2s fairly soft and when going flat out with the bases level they really do start to chatter with sideways movement of about an inch each way.
As said above - the best remedy I found even in a full crouch is to engage the edges just a touch and do very shallow turns. Stable as anything then. So if you're just off somewhere snowy come back and post a snow report of your own and we'll all love you very much. I'll pick them up later in the week!!! You know it makes sense.
