[Spending my Holiday money on susp rebuild]

Suffered a failed trunnion yesterday on a narrow country lane which created a long major recovery  !!

anyhow ive decided since i am doing the trunnions, and vertical links plus all sundries associated it may be opportune to fit new springs and coils 
will save labour costs  i guess.

so any thoughts on Koni, Spax or Gaz or leave as standard ? polybushing all round seems a good option as well i guess?
anything else i should replace whilst in pieces hub bearing kits? 
i seem to be able to get all bits from Rimmers rather than piecemeal buying from various suppliers  . shame no one does a complete kit  😞 
any  general advice would be welcome please   bit new to this ........
