Hi,
I hope you don't mind a UK blokarter asking on here, I'm trying to get advice from people who are not direct competition (unless some of you are coming over for the Euros?)

I've been blokarting for a couple of years and racing for 12 months in production, the general advice is forget the actual kart, as long as it's straight and the wheels spin freely it's not worth fiddling with, the sail shape is the most important thing.
With this mind I'm thinking about getting some performance batten adjusters (allowed in production in Europe), do you need adjusters on all your sails or are they most effective on the 5.5 and the 4 meter sails? Do you put an entire set on one sail or would it be wise to put them on the lower battens only (trying to save cash

)? I was thinking 3x on the 5.5 and 2x on the 4m or maybe 2x on the 5.5 and save one for the 3m if that makes sense?
Any advice would be appreciated.
