If the limit is reduced to 39/40 as is strongly rumoured and a number of the top riders dont continue in the PL then 5ish point riders that are capable of more will be the most sought after IMO.
In that scenario having 4 of them meaning 1 is always at reserve as well could be the way to go with team buiding.
So something like
Barker
Covatti
Sarj
Gino
Cam
Ash Morris
Danyon
If the limit is a little higher replace one of the 4 with Wells or the like.
