I want to post something here I really do but I'll refrain. They do indeed take spyder barrels, the hoses come that way from the factory mine did too I think they do that so they don't get messed with in shipping. That is indeed a WGP reg, I pulled mine apart and it even had the colored orings in it. Neat little markers but the lack of a clamping feedneck and poor US reresentation can sometimes steer people away from these unique markers. I really wish they came with an owners manual and spares kit. The online owners manual is ok at best. Mike at power ball is awesome and so is his customer service, if you need anything he'll definetly try hard to help you out.
