Well xevu it is a Therion DNA 166 and as far in the cooper goon I totally love it to be honest with ya . I got them both today so I can't really tell you to much about it just yet . But so far the goon is amazing rda the flavor is great from it and the clouds are good also . And it's pretty easy to build on and easy to wick up . The cooper goon would look so sick on that mech tube xevu I'd say go for it
