Yeah. I have to keep crafty stuff to a minimum, living in an apartment. I could really go out of my way to find some place away from home to do it, but I'd rather not. Plus there's simply no room for it at the apartment. I'd want to be able to use the track anytime I feel like it.

Yes indeed. Weight is definitely a factor.
That's why I plan on keeping the weight same, if I'm trying to find aerodynamic improvement. And/Or, having the track shaped in such a way to favor aerodynamics over heavier weight. Hey, I have time to work out the details.

Clearly, aerodynamics do matter with Pinewood Derby (did you read my first post?). Sure, it's measured in fractions of a second, but with a enough repetition and an accurate test track, aerodynamic improvement will become evident.
And yeah, there's no way I'll have room for my own tether track anytime soon, or convince the lady to use our backyard for it.
Also, as you get faster and faster, the need for downforce arises. At normal speeds, simple streamlining without downforce is the way to go. I figure, if I find aerodynamic improvements in pinewood derby, it'll just help that much more, the faster I go.
But I'm not averse to making a mini-windtunnel. That's something we'd actually have room for right now. So I may just do that.
