It's worth a shot, but a car properly setup with a spool will be much easier to drive in traffic, and when pushing the car really hard. That one hairpin can cost a lot of time in the end if you mess it up. I feel a spool will be more consistant as well since it is easier to drive. Even if the fastest lap maybe be a tad slower than a one way at times, Its better to do that lap over and over again rather than one slightly faster lap and one BIG crash hahaha.
