Longboarders: What trucks should I get for my deck?

Any longboarders? I know you guys are out there!
Anyway, I have a Loaded Vanguard with really old Gullwing Charger trucks. I want to replace the trucks but don’t know what kind to get. I like moderate downhill, carving, and I like to be able to do some simple tricks. Any suggestions on what trucks I should get?

(Right now I’m considering Seismic or Original trucks)
