Maybe I misunderstand exactly what you mean by this in the strict sense, if
so, could you explain further about wind knots on the delivery-cast?

Can't say exactly why they occur but they do. So often after a bit of
false casting with a good rhythm )to build the revs up) some casters put
that good bit extra in the delivery cast and that's when the trouble
occurs. That is the only way I can describe it. I don't think it
matter whether the fly is weighted or not.
