Get a used rayne nemesis off your local longboarding forum and stop asking stupid fucking kids stupid fucking questions on NS.
Giantpanda has a couple things right, except wheels and trucks. Everybody else fails.
Get some s9 70mm racing formulas and you're set for wheels (be warned they wear fast when sliding but SMOOTH).
Pink powerballs are another good option. Retro freerides (green) and maybe 80a (white) landy zombies.
There are more options, but I'm not going to bother.
Trucks go with whatever you want, bears are not good for downhill. Personally I'd go with kalahani's or aera's but they're miles out of your price range, so stick to bears, paris or randal, they're all about the same. Paris aren't more "carvy" it depends on the bushings and baseplate angles you're running.
Stick with rayne, bamboo boards that are stronger and lighter.
Fuck NS really has no clue.
