In all these years I have tried more than one pacenote book, but I find that the +Note ones are the best. First of all because of the paper used and then because they have everything you need for a race.
I discovered the +Note co-driver pacenote book thanks to Stefano Farina and some other friends who were already using it.
Once I tried it for the first time, I started liking it straight away and since then I have never gone back.
