Because it's available Bryn!! It's like saying that because I might use a brush and dustbin to clean my carpet then a friend brings round her dyson I won't use it to clean because I always get on my hands and knees and sweep ................. ok not a good example but u know what I mean!! New technology, it's gotta be used to benefit the sport, perhaps a better analogy would be that way back when u might have used a bleeding megaphone for announcing speedway, then a wired mic system was put in one of the stadiums but you wanted to carry on using your megaphone cos that's what you always used! ??????
That's not what I saying above though, I just think that ex-riders "should" make better refs, I dunno about Mick Bates, he perhaps blows my theory out of the water LOL I guess they would all referee by their own standards type thing.
