Some of the B&J tracks are just great, excellent competitive racing. Others I think are just a wreckfest, like the rosette one where paths keep crossing in the middle. You just end up with a big pile of wrecks in the middle and racing to gain points or even finish one clean lap becomes itself pointless.
Now this may work when there's 4 or 5 mates racing in a private sess together, but opened up to the public and 12 to 16 racers, it's carnage. In my view, this track should be retired.
