I'm looking at getting a Rocky Mountain Altitude 50 2009. I've seen that these are nicely discounted in a couple of places but from scouring the internet I can't find many reviews.

I'd be interested to know if anyone in here has one or if they have any opinions (i.e. tested one and decided not to buy).

Don't do it!! I had an ETSX limited edition that was brilliant I now have a Slayer Team that is brilliant and looks class.
The altitude looks shocking the paint job they are known for has gone!!
it looks too much like a shocking spesh!!
