If I had to choose one size I'd go for 9/16" on the blade and 1/8" beads. Opossum hair is soft with a blend of white, black and translucent hair. I had been ordering Awesome Possum zonkers made by Wapsi but decided these strips were too expensive and ordered three pelts for $45 with free shipping. Now I have enough to last a long, long time. Even dyed a couple patches, neon yellow and pink.
