Depending on what you're doing here are my top 3 for each:
DH:
1. Hellcat
2. Evo
3. demonseed
freeride
1. Drop speed
2. nemesis
3. hellcat
I personally own a hellcat and a drop speed, they are at the top of my lists, because i find they ride the best, as well as many of my friends (I skate with all the Rayne, Landyachtz team riders). For wheels Lime bigzigs are a good bet, or Orangatangs, which wear MUCH quicker. Trucks, go bear, very carvy unflipped, pretty stable flipped. INVEST IN LEATHERS if you want to do DH, it's completely necessary unless you want a skin graft. I'd also like to note that if you are tall, you can ride a demonseed all around, but it's huge otherwise.
