In this Q&A Mark Crossfield is asked by Scott McDade on Twitter; "In reviews, you often say you could game that club, what's the defining factor of actually gaming that club?”
Mark is in the lucky position where he gets sent nearly every club on the market, so he gets to test and find out what works best for him and his game. When Mark says I could easily game a club it means he really likes it and thinks it is one of the best on the market. Sometimes he is happy with the club he is currently using and sometimes he likes a change.
