Another big Innokin/myepack fan here.
I ended up with both the SVD and the VTR and have been really happy with both.
Just be careful, it`s quite easy to contract V.A.D. (Vaping Aquisition Disorder) especially on myepack.
You can get quite easily carried away, especially in the early, experimentation stage, I`m still there...
And i STILL really want the Innokin 134.
I still go back to by Vision Spinner on a regular basis though (when the Mrs hasn`t run off with it).
As many have said, the best device is the one that keeps you from going back to smoking, everything else is just Gravy.
