I am looking to find some of the top bloodlines in the barrel horses.
Any traits with those lines would be helpful.
Thank You.

Sorry, Do not really understand the question.
If you are looking at standing a Stallion-PLEASE DON'T- there are already to many horses being produced for the industry to absorb now.
If your looking to breed your own competition horse, you really need to match your mare up based on her strengths and weaknesses to that of the Stallion then look at pedigree compatibility.
If you are just looking for current standings try;
Barrel Racing at Barrel Horse World, Barrel Horses for Sale, Barrel Racing Forums, Equine Health Articles, Western Tack, and more

I would look up come of the top barrel horse trainers and see what bloodlines they are riding Good luck!
