Hi,
I am from Slovakia, but I didn´t really have a chance to ride at the Strbske pleso, yet. It´s pretty small resort, with some not quite steep runs. I think it would be pretty carving friendly, but there is this weird tendency, that the ski and snowboard begginers are looking for chaep resorts so this resort and the other resorts in High Tatras (Vysoké Tatry) are often overcrowded by straightliners plowing their way down the hill. But this probably won´t be an issue during the races :)
Unfortunately, there aren´t any really good ski resorts in High Tatras, since it is the national park, and it has the first degree of nature conservation. That´s the reason why there are only a few new slopes being built. However, there is a hope, a big project is now waiting to proceed through the bureaucracy and hopefully they´ll build some great winter resort in there soon.
The Jasná, in Nízke Tatry is much better, than the Štrbské pleso. Alpine skiing events are being held there.
I´m thinking of comming to the deaflympics and watch the PGS races, if i have enough time. Good luck at the races!
