Unfortunately the choices for guest were very slim pickings, I think Rowe was worth the risk as he rides BV well and has been in pretty good form, but it didn't work out. Other choices just weren't in the same ball park.
I also think you really need to get out of your black and white world and stop constantly hammering team managers for their choices every single meeting, you keep calling them out for mistakes without really having a clue what goes on in the pits. Perhaps you should ask one or two if you can shadow them on a race night to see what actually goes on rather than being a Clever Trevor from hundreds of miles away.
