If we would have a more versatile runner between our numerous runnertypes, we would have less problems to elect the right for special icecovers.
Ice covers make the problems.
Another point of view is the different cross resistences of our runners if they must cut through a given icecover. Two years ago the European members of the Technical Committee wanted to through out the 4 mm T because they can be substituted with a little bit more resistance by our thin 4,8 mm slotrunners. Unfortunately there was only a simple and not a two thirds majority in favour of our proposal. Like Bernd Zeiger you must now buy an additional set of 4 mm T s if you want to be competitive in special low wind conditions with little snowcover in comparison to other thin T runner sailors. Imagine we are able to find a more versatile runnertype which is able to substitute two or more other types completely and we start a period of searching such a runnertype like we did it with masts, I think it would be a benefit to our class to.
