So I'm thinking of doing the Mammoth Masters program this season as a way to improve my all mountain and off piste skiing (see another thread I posted in the training forum) - a whole season of coaching with continuity sounds great. I have never been on a race course before (yes I'm aware I have to try out for the program - I'll do some training with an instructor during November). My goal is to improve my own skiing, not to be competitive against other people. If I get bitten by the bug then I'll go buy skis. But if it's possible to learn and improve my skiing on what I already own that would be great.
Will any of the following three skis I already own work for the first season, or do I really need to just pony up and go buy race specific skis? As for boots I have Lange RS130's and Dodge carbon fiber boots, so I think I have that covered.
Me: 6'0 170 lbs, 35 y/o male
1 - Kastle MX 88, 178 cm, 20 m radius
2 - Nordica Hot Rod Nitrous Ti - 78 mm waist, 170 cm length, 16 m radius
3 - Atomic Beta Race 9.20 170 cm (15 year old GSskis sitting in my locker, but I bought them new many years ago and put maybe 10 days on them)
Thanks for the feedback.
