What are the concerns about it? travel,geo,design?
Without looking at geo charts etc the biggest variation is going to be the suspension design, pivot points and leverage.
I love the commencal design cant fault the feeling of having more suspension when you need it and less when you dont. feels awesome. I have ridden a VPP only a hand full of times but they are also a very nice feeling design, I was on a V10 though so it was hard to compared with the travel variation.
The commencals do get brake jack, owning a supreme DH you do notice it but it tends to be from poor technique, brake jack stiffens up the shock under braking making it less reactive to bumps hence becomes stiff. This is not a issue though if you brake correctly, you should not be braking in rock gardens or in rough sections/corners, all braking shoul dbe done prior to these sections as it increases grip and allows the suspension to do its job without other forces acting upon it. there are times when braking in rough sections may be neccesary, I have found two things though.
1.The brake jack encourages me to get off the brakes, although it may feel sketchy I know the suspension will perform better and gives me confidence in it. The commencal on top of that is a bike that rides better the faster/harder you push it so its not a bad little combo if you can convince yourself to stay off the brakes.
2.You get used to any feeling your bike has like with any bike you adapt to its handling and brake jack is the same.
With two bikes that are quite different in suspension design your best bet is to ride both. But to answer your question in short the nomad should be more than capable. dudes hit 30ft gaps on hardtails, if they are smooth enough.
