Slicks for indoorracing.

[Tjompa]

Hi!
Will there ever be a decent slicktyre from Schumacher?
Here in Sweden we use the minipins and spikes as a controltire at the competitions, we also make them into slicks on our own with lots of rubberdust in the nose as an result. We are so tire(d) to do this and the whole Swedish buggypopulation would need a decent slicktire. Is this so hard to produce? I have tried the venom88 but that really sucked compared to a slicked minipintire....
I am also tired of them balooning after a while, the rubber is really not suited for tyreadditive (spelling?).

Happy for lots of answers!
