To the OP, I assume you've just got an Alpine trail....?
With what you've spent, and looking at the spec, nothing needs changing. At all. Okay, saddle, grips and pedals are personal choices, but the functional differences between XT, SLX and even deore are now extremely marginal. get out and ride the damn thing!
you've got a set of forks worth maybe £800.... they're nearly as good as they get without getting silly. Seriously, that's a hell of a bike.
FYI, what the others said is true, Hope stuff really is MADE in the UK, not just finished or assembled. I love it, and for the quality, I'd agree that it's decent value. But, don't fall into he trap of thinking that all MTB companies are owned/run by the same people as the 90s... Nukeproof didn't *change* as much as the name was bought by a larger company; in this case, the struggling brand 'Nukeproof' was bought by chain reaction cycles. Hope, however, are still the old, awesome, Hope.
