My first day I had a blast. I was a child, had done some sledding and snow fort building. The whole first day was going straight down into a small ravine and up the other side. There was enough pitch to move, to be fun. You stopped by going up the other side. I learned to go straight and survival side-step. Nothing more. I remember being scared of "The big hill". Unknowingly, you also learned to stay over your feet, and adjust as needed. I watched my siblings successes and failures. I don't think equipment weight mattered that much. And what little there was probably mattered most when side stepping, lifting the ski over and over.
I fell a lot. There was no lift ticket. Mom and Dad were my completely amateur instructors. We lasted about 3 hours.
Weight doesn't matter when you edge a ski.
Weight doesn't matter when you apply rotary to a ski (Enough to matter at a beginner level)
What else is there to matter to a beginner?
Boot fit, ski length, physical fitness and appropriate terrain matter far more.
