Defender help

[billnats]

Theres plenty of topics out there but obviously the players I have are slightly different (still apologies in advance).

I have:
Deledio, Goddard, Suckling, Birchall, Waters, Dempsey, Smedts (Spurr & Darley).

Going to upgrade Spurr and keep Darley/Smedts as back ups. Dempsey will stay until finals.

I have 500k in the bank so money is not an option. Do I go for:
Carrazzo (super cheap)
Scotland (super reliable)
Shaw (wait a week with his BE so high and get his big scores)
