For a double loop - based on kickoff times, Taumalolo has to be one of the loop positions - we'd only do that as insurance against a 5th minute injury.
(could also do Bateman or RTS, but that would mean definitely playing Burns, which doesn't really work)
So I think just loop someone who plays before Souths with Brittain in 17.
AFB would be my bet
Sub in Burns or Staggs if he sucks.
