My first rdas were a Tobh, Plume, and Magma. The plume is probably the easiest to build, with the magma a little more difficult, and the tobh being slightly more difficult then that (due to the three post design and the airflow fin, you have to position your coil a bit differently). I agree with what others said though, the velocity by all reports is great ( waiting on mine), but its not a standard design. I'd get a four poster and three poster and try each and see which you like and what was easier to build and position on.
