Don't you mean you need to upgrade F6 instead of D6? You have Langdon as D6 and Cameron as F6. Great team by the way!
Nah D6 (Langdon) and M8 (Halihan) are all that are left to upgrade after next week.
F6 (Lloyd) will be upgraded next week to Spuddy.
Cheers for the compliments about my team too mate.
