Can't see the John clear enough to get you a definitive answer for him, but Roger and Brian are fine. Roger went with a very simplistic example of his hand here, which I don't like but it does have a confident flow. I would just wait for a better example to come along. There's no Freddie on it, so it doesn't have much value and Brian and Roger are generous signers.
2 to 300. Brian and Roger are a dime a dozen. The value here is in John as he no longer signs in person. He stopped over the summer. I don't like the John on this one but the flow is confident, so I'd say its genuine rushed. Not ideal, and I would advise waiting for a better example.
