When you're into aggresive skating, want a lightweight plate, with a lot value for money, the Sure-Grip Avenger/Avanti series might be a good choice.
The Avenger is perfect for ramp and bowl skating, with the 33 degrees kingpin (Sure-Grip named it a D45 but it is really 33 degrees).
Because its 33 degrees the plate is more agile and has a faster response than other plates, because your weight is more on the pivots, which makes them less stable but provides more agility.
The magnesium version is also an extremely light plate with only 220gr for a 150mm plate (factory specs)
