I thoroughly approve of your name. My older daughter is Becky or Becca! I strongly suggest the following:
Find a high level intermediate ski. This way, as you improve you won't out ski them and have to go back to the store the very next year. This plus the proper length... just slightly above the head or at least not lower than forehead/hair line. These two items will give you higher speed stability. Original price will say about $450+ price range for the high intermediate/low advanced ski. They are stiffer but not so much that you'd have trouble turning them.
Take the same run at the same speed first with an entry level ski, then a high intermediate ski. You will find the lower level ski will feel like you are on ball bearings! This is a very scary feeling!
Now for you.... I would like to see you try this- Take a run strait down... doesn't have to be a steep hill, just moderate... and notice your ski tips floating around in front of you. Now- put your hands up in front of you, arms half bent, thumbs pointing downhill(this gets the poles behind you), and arms half way between your shoulders and hips. Now relac your elbows abit. Notice how your ski tips came right together and behaved themselves? [img]smile.gif[/img] Now drop your arms again and notice the tips floating around again. Now do the arm and hand thing again. The tips behave themselves once more! This is only upper body balance, but very important. This will also give you and your ski more stability!
Good ski positioning- what I mentioned above plus- bent spine (flexing from the belly button, not bending over at the waist no matter how much you feel you want to, shins against the tongue of the boots, tuck in you behind (I see many beginners stick that behind way out there), and there ya go!
Do not plant that pole .... just kiss the snow with it. If you plant it hard, it goes by you very fast, pulloing your shoulder back and that throws you into the backseat again! Tips then come out of the snow and you can't turn and they float on you again.
Now... on those little trails which go between runs which are so packed down hard you can't even get your pole into the snow to save your life... Your skis will float no matter what you do. There's nothing for the tips to get down into to track straight. They will float on you in this case. This is not your fault. All you can do is fuss with it until you get over to the next run.
