I keep giga charged, but I don't get to use it much against the guy I 1v1 with. A block, or staying in the air a lot don't give much of a chance to use it for a stun. I keep it charged in case I need to get out of trouble, close distance fast, or to try to punish. E.Coles force projectiles are so slow on startup, and tickle lightning makes his only useful projectile the grenade. The up tripwires have their moment, useful for forcing someone to move in a particular way.
I started using Good Cole lately, he's much nicer since his force projectiles startup faster, and he have nice abilities that can actually hit people easier.
Don't underestimate the tickle lightning! Its one of my favorite attacks. Easiest way to get the sliver of AP to a lvl 1. It also keeps drakes barrel at bay and breaks sir dans shield quickly.
