It depends on what you are going to do while your there and the reson for going. I've been a couple of times. The first was with a DH bike and was fun but a bit repetitive. Pounding the pleney and the les gets wc tracks just gets boring, and when it rains, jesus! 😯
Last year when i went, i went with a load of trail riders, bought a route book (although the les gets tourist board map is excellent!) and did a load of xc routes. It was really good fun. It was all lift assited and we were able to cover imense distances! On the rest days we could just do some DH that was near by.
As for your bike it would be able to do it, but you would be limited to green or possibly blue routes, much more than that and you would struggle, depends on what type of rider you are and what you are capable of? If you are looking for a new bike anyway then consider something with more travel than yours, i've read that the new 140mm travel FSR's are meant to be very good as are the Scott Genius (150mm) and can be extremely light that help maintain the 'quick' feeling.
A good piece of advice i had off someone on here made a lot of sense, in that all your doing out there is riding just as you do here, the hills are just bigger! If you see something you don't want to do, do the same as you would here and either look at it a few times and don't do it, or think **** it and go for it, either way its still the same 😆
