I would have to say if you want to be a prostaff you obviously have to have the experience in the field, proof of skill and experience, so there for a few nice bucks/bulls under the belt, have to have lots of knowledge in lots of the fields in hunting, be it deer, elk, predator, bird, so a well rounded hunter.
You also need to have the time to attend the shows, and be willing to travel. I got a couple of friends that Prostaff, one for Drake Waterfowl, and the other for Avery. Seems like they both do a lot, for not much in return, other than discounts and the title of Pro-Staffer. Both of them are members of Huntingnet.
