Update for those who are interested.
I got one last week and have had a couple of local jaunts on it.
Tyre pressure – not managed to fine tune this – they put far too much in at the shop – I am letting air out and using the very scientific thumb test to see what pressure there is left!
Its not as heavy as I was expecting! – will be going tubeless in the near future – the shop tried with stans valves and had problems so I have bought the WTB ones to have a go.
Its pretty good downhill – had a couple of good downhills on it and was close to times with my old orange 5!
Happy so far, might experiment with wider bars and shorter stem as mentioned above – a dropper might be good too!
