Bamboo gt turning tightness-

just curious how small a turning circle can you guys do on the bamboo gt or carbon?
This is a regular turn standing up; not sitting down or skidding. I think mine is about 5metre plus! Not very small and need a wide arc when making a left or right turn especially on the foot path!

Can't actually kick up the board from the back to do a sharper turn.
I feel my trucks are loose enough where I hit 20ish km/hr starts to wobble.
