Animal one hole gold plate and a Blue plate clone with weenie pipe would be very close, If I had to choose I would run the animal, now Blue plate clone with big pipe different story then I would run the clone.
black plate -- I'm still going with the animal is my thought...
Replied to your other thread asking what gold plate is .575"
Let us know if this is some sort of local option (or possibly you meant black plate?)
.575" is a flat head gold plate size -- maybe some confusion on the rules?
