I was sent the Axial pro dual by mistake from Twisted Messes and told just to keep it and I'll be sent my proper order. Now that I have it, I'm curious about the series deck. In what situation would I want to double my resistance? Wouldn't that just require more battery to run. I guess maybe for mech, but for a regulated mod that fires down to a .05 there really isn't much use for this deck...is there?
