Hey guys - just to clarify about the VPC WarBRD and extensions.
The VPC WarBRD is designed as a desktop stick. The cam profiles and the spring strengths are designed with desktop use in mind. The max deflection angle of the VPC WarBRD is also larger due to it being designed with desktop use in mind. If you use extensions, the overall stroke length would be quite large and could lead to clearance issues. Because of this, we do not recommend using extensions.
It's not a question of strength or quality!
