[Rob Wright]

Aside from resalability considerations you should take a long, hard, honest look at how you intend to use the car & compare that to the complexity of each package before you commit.

Part of that statement includes your potential desires to build-up or modify it down the road & what that might entail.

If you're more of a "screwdriver & timing light" guy but likely to want to tweak on it later, you should avoid anything that involves complex tuning requirements.

You should also consider how much work you want to do at the track for between-round prep.

If you don't mind extra steps for cooldown, etc. the supercharged car might be a good choice. If not, stick to the NA combination that satisfies where you fit in the paragraph above.
