anyone can recommend a good male and female steers for GWN? or just use GWN staff members?

contact GWN and they can assist you

if you use the GWN staff members it's free.. however if you want the same steers person for the entire weekend it will cost you.

GWN as far as I am aware does not provide steers.
They may have two steers in case crews trun up and require one,
however it is a lottery if you get the same one.
And, they are usually not members of the coaching staff.

Its also possible you get the fat steers.
