mate big wheel they do work you do not have a clue, Oliver doesn't ride long and neither does Newitt or Symonds, Munce rides very short, you are one of the Murrihy Know it alls, I would rather put my faith in the Top Jockeys who use them, somehow I think they would have a much better idea than you and me, they think they work or they wouldn't bother using them!!
In saying that I do agree with you as far as the use of them behind the barriers (and in trackwork)goes,
Now I have stated it before and I will say it again!!
I am totally against the use of spurs and think they should be totally banned and treated like being caught with an electrical device, they are cruel no matter what else you think about them!
I just think if a Jockey is going to put them on on some horses and off on others we should be informed when they cahenge, there should be Jockey gear Changes
another "gear Change" that I would like to see listed is what vet was treating each trainers horses, I think this would be a revelation
