Hmmm - well i;ve just looked up numbers for last weekends SoT meet at Mallory with New Era.
The numbers featured in the race were :
49-131-168-6 ( thats me buggered)-143-169-155-56-106-38-135-66-129-78-150-139-153-152-119-133-82-90-166
The numbers were pretty similar for Brands too with the addition of 5 and 7
Gonna be luck of the draw i'd say.
