Seem to remember at least one Holder getting injured training on a moto cross bike pre season, and although after he retired Lee Adams fateful ride the desert. I think in general top speedway riders put their fearlessness before moto cross ability.   

Who are you referring to?

I liked Jamie well enough as I knew him in his mid teenage years and he was a tidy enough rider at NL level. With Phil Morris in his corner he could have and should have gone on to be a decent PL rider. However at times he would just disappear despite being given several chances to put things right by Tim Stone and Pete Towersey.  He was well known as somebody not to cross in the rougher area of Newport I was told by quite a few people and most certainly in the Mallet era stopped the local thugs from raiding the Speedway stadium on at least one occasion A shame he's ended up where he is today but we all have choices to make in life and some seem pulled towards making all the wrong ones.

Depends if he is realistic with his demands I would guess

The only person I would believe here is Andrew. I would bet if there was any truth in it he won't be owed anything now.
