I use a bit of 90mm pvc tube with a screw cap on one end and a glued on cap on the other. 2 meters is max but mine is just over and i don`t get any knock backs. and as long as all the luggage comes to a certain weight i don`t think you`ll get charged for extra baggage unless things have changed since my last trip on the plane. oct last year. Pistol Pete has fished hamilton land based so give him a PM as i`m sure he will be keen to help you out. Cheers Andrew
