Replying to Help to buy skiis

Hi, the most difficult question I am facing right now while researching the most suitable skiis is the level of skiing competence. I am trying to buy a skii and I read that that pariticular  skii is designed for an experienced novice:))!!!? or... insecure expert. Please help. Also, once you know where you stand on the scale from 1-10 how do you take under consideration the age factor ( power?) which is so diffrent at the age of 30 and later on at the age of 65.
