No, you don't need 200 watts unless you want to vape that high, or you happen to like seriously massive coil builds. Sigelei, Snow Wolf and the SX Mini all make one in the 60-80 watt range and solid enough to do just about anything that's not extreme; and smaller as they are single battery. That said, you never know when you'll get a hankering for some 20ga super duper triple twist left handed monkey Claptons, or something, so it's kind of nice to have it in there just in case, and if you don't mind two-battery (or three, the Reauleaux is also a good choice) mod.
