IMHO it needs to be all rubber mounted, or all hard mounted.
If it's half and half the hard mount is going to take all the stress and is likely to fatigue fairly quickly.
I've gone for a hard mounting solution now, similar to Stots.
If I were starting from scratch though I'd probably use polybushes in the arms, and bolt the nose to the chassis via bolt isolation bushes.
That way it'd be nice and solid, but still have a little isolation to reduce vibration and potential fatigue.
Whatever you do, just don't use landrover mounts in shear
