Can Watts ever be "wasted' if they're unused? I mean, I imagine on some of my larger mods I get a bit of battery decay, perhaps but do I really care? I am not sure.
If you're fat though, I could see a real actual 300 watt starter kit to be useful in the kinetic energy you burn.
If you are fat AND a masochist, just go for the 200 watt punk kit, it was like doing self-injury all over again.
I have never heard one peep from the dude I sold mine too, so either he's dead from all the bandages on his hands, or he hates me. IDK.
