You really won’t know what sort of track you want until you drive it.  Try a few different layouts to find out what you like.  Also try your cars with and without magnets because the driving experience is very different.  Non-magnet means you need to do a little prep on your tyres but it can be very rewarding with the added bonus of slower lap times but more controllability.  But if you are after speed then keep the magnets.

I tried 3 or 4 layout options before I settled on my favourite and it was different from my theoretical favourite.
