Anyone have some insight or experience with the impact of ski weight on performance? ... ski mostly hardpack groomers and trees, but looking to work on mogul skills this year ... I'm worried about the lighter ski betting "blown around" by the chatter of GS-style turns and speeds. Should I be concerned?
In a word, yes.
How much? It depends.
A lighter ski will suffer from more large amplitude high frequency vibrations when going over uneven surfaces, but if designed well, these vibrations will also damp out appreciably faster than a heavier ski (everything else being equal, which, of course it never is - grin - the heavier skis often are heavier precisely because the have more damping layers or components). It comes down to a feel. Some people like 'em light and lively, some people like 'em smooth and silky. Your call.
That said, a ski that is optimal ski for GS won't be optimal for moguls and visa versa.
As you obviously already know, you want the mogul ski to have a much lighter swing weight (ie, the ammt of material out near the tip and tail), and be considerably softer. The good news is that modern skis can be pretty short and still do very well at making recreational GS turns. This "pretty short" factor goes a long way to making such skis work in the moguls. For example, a lot of people adeptly run moguls on skis like 170-ish 11.20s which are relatively stiff, light, and have a GS-like 20 m sidecut and great high speed performance.
OTOH, you will never get a soft mogul ski to do well at GS.
