Thanks for the feedback, interesting that both the yt and orbea seem to be designed around the BOS yet the Orbea was has a linear leverage ratio while YT went for a very progressive one. Maybe the YT uses a larger air can than the Orbea?
This is all getting confusing, I'm slowly going mental! Updated thoughts on each below:
YT Capra- L = Wheelbase1196.2, chainstay 430, Reach 445, stack 602.5
Value is great and the BOS does apparently make a noticeable improvement over standard fox/rockshox. Still not sure about the sizing for 6ft2, perhaps I'm getting too wrapped up in hype around long and low geo. The bb is still quite high (or not super low which I know I prefer) - just over 350.
Orbea Rallon- L = Wheelbase 1204, chainstay 420, Reach 467, stack 624
A lot of money. A pound heavier than the others. Probably the least pedal friendly. I like the idea of the geometry. BOS suspension. Large sizing seems like a good size for 6ft2
Enduro expert 29- XL = Wheelbase 1209, chainstay 430, Reach 465, stack 655
Always reviewed positively, light, big wheels with similar geo to the others. BB is high ~350 but could be lowered without making the front too slack. not great value for all the own brand kit. Seems that only a monarch plus or a cane creek can be fitted aftermarket.
Still leaning on the Enduro in XL with the ugly drop stem but could be creating the long 29ers that everyone hated a few years back. If I went with the reduced length monarch and offset bush the bb gets down to around 340 and the reach and stack are 458 and 660 respectively.
My riding - based in Australia at the moment mostly riding shuttle assisted rocky xc routes. Bike needs to be capable of riding smoother singletrack but that will be in group rides and not too quick. Will be trips to NZ and the european alps. I'd probably sell the DH bike too so this would have to be capable of a few DH runs.
Test riding opportunities are limited here - the enduros are sold out before they get to the shops, the orbeas take 6-8 weeks to get in and the yts aren't available until may and would require a friend to resend to aus from europe.
Anymore pearls of wisdom? specifically sizing info from any 6ft2 people who have ridden similar size bikes and/or general comments on the relative merits of the bikes.
