I got a lot of "Quality" but none explaining why and what is considered "quality". Anyone?

I don't think the quality of a boas tail can be counted in saddles just the colors and patterns
Hmmm, can you go a little further with this thought please? I think I understand, but my mind is REALLY tired right now, lol.

I'll post after enough answers why I want to know. This isn't a vain empty poll. Thanks!

Maybe some of you who own red tails can tell me how many red saddles yours has! That would be helpful too! Thank you!
