If you are going to buy a beginner ski, spend the least you can on it.
If you never believe that you will upgrade to a tippier one, then the heavier one you have would still be just fine and last a long time as well as take the knocks.
If you do upgrade you will loose less money in the process.
A real life situation I have seen, is a beginner buying a carbon V10 sport.
He then sold that and got a carbon V10.
Had he purchased the cheaper layup sport, he could have kept the sport as a second boat and still paid no more money overall.
Follow the path of the independent thinker. Expose your ideas to the dangers of controversy. Speak your mind and fear less the label of 'crackpot' than the stigma of conformity. And on issues that are important to you, stand up and be counted at any cost.--- Thomas J. Watson
