Focus on gi or no gi competition?

I'm a blue belt. I train only no gi. At the seminar where I received my blue I played a gi game that amazed me: collar chokes, spider g., control etc. (don't want to sound cocky). I'll be at a competition both gi and no gi. My gi w. class is: 76 (167 lb) - 86 (189 lb) kg (blue belt), my no gi is: + 76 (167 lb) kg (one div. - meaning beg, int and adv. together). I'm 83 kg (183 lbs.) . Witch do you think I should focus on? Gi or no gi? Thanks!
