The Heartcarve Custom Piste is here... at least in design.
It's about a closed off run just for heartcarving, or really any type of skiing that fits you best.
Skiers can also get a score, so it could be turned into a competition, but there is some technology and a person required to judge it most thoroughly.
Theoretically, you could just go straight down and get as much speed at you want, but that misses the point (and fun.)
This thread continues from the Meathammer 2015 thread, a ski that I think would be ideal for the HC Custom Piste - but not wholly necessary. I just think it'd produce the best results.
