A standard springer can not have a Kort nozzle, if you read the springer thread it is mentioned in there a couple of times. If you fit a Kort nozzle it goes under the name of a super springer, as does any deviation from the basic design.
If you want to bring your super springer along to the weekend great, I would love to see one fitted with a Kort to see how it performs against a standard springer, but no football. If you want to play football you can always borrow my one, I am sure there will be more than one game during the weekend.
