Hello! This may seem to be a stupid question, but for the new Babolat AeroPro Drive Bags professionals that are not Rafael Nadal, will they use the 9-racquet bag or the 12? The only reason I am asking is because the 12 has the Rafa signature on it, and I don't know whether or not players use equipment with other player's signatures, logos, etc. So simply, so any pros besides Rafa use the new 12 racquet bag? Thanks.
