Check DC rules
For all Ties in the World Group and Zonal Group I the court surface must be of a type used in a GS Tournament or in a minimum of three tournaments in men's pro tour held in the year previous to the tie.
And pro tour event must have a prize money of $350,000, meaning it's an ATP World Tour event, not a Challenger.
So, allowed surfaces in World Group and Group I are hardcourt, clay, and grass, but not carpet. And, Taraflex is classified as carpet
. So that's probably the reason for not allowing the use of it. Which really sucks.
Btw, in Group II, Poland seems to have used carpet a lot. (Click Team Win/Loss
thank you, that probably explains why the USA and Czech Republic when receiving Spain could not use carpet as the French did, if this rule was already in use
in the old time, it was a matter of having enough tournaments played in the country
on that surface.
I was so surprised when I saw that the surface the USA did receive Spain on, was not really fast
The Spaniards had whined so much before the tie, maybe they got what they wanted then.
I remember the old DC ties played on wood
