Peggy, Funny thing is Most of those ranchers you listed use both Blue sparkle and blue cloud. Many ranchers in the east also swear by a specific feed and pay more for it then they could get other types of feed for. Yet different ranchers will swear by another feed and tell you that you must use it to show well.
Why because they use what works for them. Doesn't mean its the only way to do it the do what works for them. A good example is the feed. Many are changing from the recommended feed in that area due to a number of people having issues with it.
Also check the average humidity in any of those ranchers area's . What they would consider to be exceptionally low humidity in their area ,would be considered high in my area.
If you also contact Randy and ask him about the qualities of the two . He has even posted That blue sparkle is a lot finer then it used to be.
So instead of attacking me why don't you post the research to back what you have posted as fact in this thread. such as ,blue sparkle cuts the fur ect.
Any research should also be peer reviewed and published in a scientific journal to be considered credible. But any research you have would go along way to support what you have posted as to be fact, rather then your personal opinion.
