G'day, This may be a silly question but just wondering what difference the bar size makes. I realise it's probably more of a kite controlability thing but just wondered.
Bigger means quicker turning... imagine pulling two different size bars on the same angle the longer bar is going to pull the line further in as it has further distance to travel.
Quicker turning, 'twitchier' and marginally more finite control... So say if you were learning wake style you would be using a smaller bar then recommended on your kite so as to reduce unwanted movement.
