Surprised this hasn't been deconstructed on here yet?
One all?
As I'm sure you know, many modern systems have a rigid rotor head but permit flapping, feathering and dragging through elastomeric bearings - interesting that the 105 doesn't have any of those at all - the blades must have been absorbing enormous stresses from lead/lag as well as flapping.
I believe the S92 has a similar arrangement which will give you high control power and similar handling to the 105/Lynx on a slope but perhaps without quite so much potential for generating mast-bending stresses with in-slope cyclic.
