An unqualified opinion is basically synonymous with an unwelcome opinion, for some.

People who have spent their entire riding careers with jumping horses, despite their age, are indeed qualified to have an opinion on the jumping form of a horse. I may be young, but I have 12 years competition experience on jumping horses and I dont think that should be discounted because Im not 60. My opinion holds water whether anyone likes it or not.

But the horse is basically preservation bred, apparently, which is a whole different animal...
