If the choice is now or never, then obviously the answer is never. You cant have players pulled from their Counties and the supposedly serious business of the CC (and before anyone makes a comment, it is still very serious business to a lot of people) to play in a pointless friendly when other opposition could easily fill the role.
If I was a County or a player then I would be fuming.
Until recently though, the touring side used to play MCC, which was basically an England A side. Pretty sure they didn't only select from counties which had no game that week.
