I think you should stick with the helmets that use the goggles, the bike helmets look like rip-offs of CG and COP figs. The goggles are a good choice, it gives DARX figs some unique design. BTW I'm gonna make a stopmotion of Crimson Guards totally owning stuff! like ramming into enemies with their hover cars, sniping, blowing stuff up, and smacking a War Bot with a gun, then kicking it to the ground, then shooting it rapidly untill it splodes!!!
