nomads in particular need midstroke support, which the large air can Fox (in particular the DHX Air) are famous for not giving. You might want a re-tune, a smaller air can sleeve or more compression damping on the RP. Try it first but it will probably feel like it blows thru its travel and sits further in it than the heckler.
Is it a Mk1 or a newer 2nd Gen VPP? The Mk1s climb like dogs in the granny ring, every pedal stroke compresses the lower VP link effectively shortening the chain stay by about 3/4″. The newer ones are more neutral. I hated mine so much (a Mk1 and my dream bike) I sold it for a single pivot (nearly got a heckler, ended up getting an Alpine 160). Hope you enjoy it but be warned (the Mk1 also gets thru bearings quicker than the newer ones, at 90 quid a set…).
