I have read the archives regarding the 19# injectors, and there seems to be a problem with the fit of the design 3 injectors. (length, o-rings ect.)

Has anyone experienced any long term problems with the Design 3's?

If you are using the 2, or 3 series are you happy with them?

Which would you buy today?

Thanks
