A DH sled is definitely worth it at the bike park and at Paradise Canyon. Have fun.:thumbsup:
Most the trail maps for utah can be found at skidmap.com, including brianhead. Their current map is an antiquated "flowpen on paper" map. It also doesn't include any of the good shuttle runs to the top of Brian Head Peak.
FWIW...Admittedly, I'm not a DH guy (my son is) but we went to Brian Head this past Summer. It was the least favorite day of everybody in our group. We also spent a day doing shuttle runs of the top of Brian Head Peak, a day over at Navajo Lake and 7 days in Park City.
