I'm from the US and have tried all the above frames except the DYE.
The shocktech is utter crap, imo, much like alot of other stuff they've been shoveling lately. Its not only ugly, but not even tourney legal in the NPPL. The trigger is, though more comfortable than the WGP, just doesn't feel right. I can't explain it but it just doesn't , to me.
The WGP frame is sort of the mediocre of the three. THough its not the prettiest of frames it, thats merely a personal preference. Unlike the Shocktech, the WGP is quality crafted and both the black anodizing and nickel plating is perfect. The trigger however is its down fall. Its a little uncomfortable in on-gloved hands and very thin. It also lacks a lot of the adjustability of other frames. The springing are very light and smoothe.
Finally, the Blade is the one I own so keep that in mind. It is not only te most attractive of the three, IMO, but also the most comfortable. The trigger shoe is very wide and rounded on the edges so it provides a large, comfortable trigger which can be shot from and position with ease.The springs used, though some complain they are a little stiff, are snapy and allow me to get a good rythm in rapid firing. The frame also uses regular Cocker sears and springs so you can costomize it to your liking. Finally, I can't speak for the the other frames because never got to use them fr an extended period, but the Blade frame allowed be to increase my rate of fire by 50%. Also the blad comes with everything you need to install it: Extra hose, hose clamps, screws, and a nice instruction sheet.
