Jeremy.....I have 2 MT's and my 3rd Serpent just arrived. The Serpent will surprise you! The flavor and vapor production is on par with the MT. As with any rebuildable, everything depends on your build. I mainly bought the Serpent to replace my STM's and it has far surpassed that. Even with a .5 ohm build at 35 watts on my old Vapershark 40's, the Serpent rocks! I gettig ready to put a big fat Clapton on the one that just came and put some power to it!! Oh yeah, I only have to wrap one coil. lol
Like many others on this thread, I find the Serpent much more than a "suitable alternative".
DP2....the American Spirit will be done "cooking" in a couple hours. You'll prob be getting more PM's. lol
