s1mple+NiKo=insane fire power
GuardiaN=still one of the best AWPers rn imo
Olof=really experienced player who is optimal for the lurker position. You don't need to be fucking beast like s1mple,electronic etc. for the lurker, you need to have a lot of experience
Karrigan/ChrisJ=You don't need some individually better IGL when you have team like this so karrigan will fit well imo + they played with karrigan for a long time so they have built up good team chemistry i think (except s1mple)./ChrisJ is good option aswell, he is individually better also good AWPer so they can use double AWP setup, but most likely GuardiaN and s1mple will be better option.
