i started with an MVP 2 and an iGO W. I now have 2 igo w's as well as 10+ other
rda's and stilll used the iGO W's. I wouls say they are your best bet. you will need to drill out the air holes tho.
If you dont have access to a drill I would say get a stillare, they hare easy to build and have a very adjustable airflow system.
I would suggest your build be around 1 ohm using 28 or 30 ga kanthal. Single or dual coil is your choice
