OK...I am confused...I have the NX Project double tank with SS plate and wing...it is also a "donut" style wing...if the Zen is a donut style, like the NX and the Zeos is a donut style what is the difference? Zeos and Zen wings are both listed with the 38lb option. they appear to be identical, but I can't find anything definitive if they are in fact the same single tank wing. Anyone?No. Zen uses the NX wing while Zeos is the standard donut wing for standard plates.
IMHO, I don't like thr NX wings, the standard regular Zeos/Hydro are just perfect.
