Wiardgroup

Hi all

I am new to Wiard (it will mean a jump to frac rack)

I have looked at Wiard stuff for over a year now and wonder if there is 
new stuff coming out soon?

I think I hear that Grant was making a complete modular?

Has anyone banana jacked their wiards to sit in with their Serge or 
Modcan, or Fennix?

I would love a silver version of the blue panels with banana jacks ( I 
really love the blue look but am trying to keep a uniform look)
