As for the heavy rear end, blame the frame.
Yeah I was thinking that too. If you're asking us, it means you don't really notice anything wrong with it (or at least you haven't mentioned it). Don't upgrade just for the sake of having more expensive components. Rock it until you feel like there's a deficiency in one of the components, then upgrade. And of course, upgrade when you break thing.
