Thanks for the replies guys, TrailAddiction were the guys I was favouring at the moment.
flamejob, ref our time with Switchbacks, the riding was spot on, just the right balance towards the down rather than the up, as someone has already mentioned you cant be doing to much up in the heat.
They tailored our week towards the ability of the group so we got it at the more techy end of XC with enough to keep us on our toes.

The accom was basic along with the food so be prepared to take some or cash to take advantage of the cheap restaurants around Bubion.
Must give a shout out to AltitudeAdventures, Ian and Angela's hospitality last year was spot on and the trails are fantastic, so if any of your guys fancy the Pyrenees give them a call. http://pyrenees2008.fotopic.net/
