I've got a big rig/roughneck V2 hybrid, and I don't know if it's the rda (roughneck) I'm not a fan of, or if I haven't found the right build yet, but I've found my 2 other regular rotation mechanical devices to "hit harder" than the hybrid. I think it's really just a matter of the build and rda...my 6 dollar plume veil clone rips with a .2 ohm build on my aria oros V2.. Granted it is a nice tube mod (about $70), but my Hollowpoint clone (about $30) also rips.. I feel like I have to be missing something, but I've been yet to be impressed or blown away with my hybrid's performance. The build quality is phenomenal, it's easily the nicest one I have, as it should be for how much I paid for it, but as far as performance goes- the distinction is not as clear as it is on the quality front. With the comparision in price points, I like my Oros V2 better than the Big Rig..
