The majority of the shoots the FBH shoot with their parents, so do cubs. Its at the national level that its split.

I had a FBH turned cub, in his last year as FBH he was almost cleaning the course, at Peek-n-Peek at the FBH shoot the last year he was there, he shot a 98/100. He jumped to cub and it devasted his fragile ego. The sudden jump to 30 yards, where you have multiple pins and distance guessing did him in, not the competing against older kids.
