My first season as a Comets fan was 1970 (Ian Thomas/ Geoff Brownhutt brought speedway to Derwent Park)and you didn't know when attending a Friday night meeting that there would be 'Silver helmet' match races - not until you saw the trophy sitting on the table next to the starting gate. But it was good to have that extra treat for your speedway fix.
One night stands out for me about the silver helmet in 1973. Comets had heavily outscored Rayleigh, the visiting rider Moore(?) had custody of helmet so top scoring Comet would challenge the Rocket. However 4 Comets were points-wise able to take this challenge on i.e. Lou Sansom, Taffy Owen, Mal McKay and Mitch Graham - so to decide who would be the Rockets opponent the shortest straw drawn (in pits)would do the business. The announcer told the crowd that Mitch Graham will be Comets rider - at which point many of the crowd booed loudly - I recall being very very annoyed with these so called Comets fans. However the boos soon changed to cheers as Mitch won the helmet....but he lost it the next week boo hooo.
