the DX 150 wraith seems slick -what's the deal? different plastic?
it is pure dx with little to no weight agent.
as for people describing the wraith as "crashing down" what you are seeing is the effects of momentum.
heavier discs carry more momentum into the later half of the flight, forcing penetration.
lighter discs have much greater carry capacity since there is less downward force applied by gravity.
basically, what you are seeing is that you MUST have the wraith significantly nose down and turned to get it to finish nose down and penetrating forward.
