Fonz,
What don't you get? As long as you hold an ATPL (which requires 250 command), you can hold a command in a high capacity RPT aircraft. The kicker is that if you have less than 500 multi command, you can't be PIC of a low capacity aircraft (like DH8B for instance). If pilots in that boat end up with a command, it will be interesting seeing how the company manages the restriction, as it will mean that ops may not be able to "downgrade" flights to a 200 for some junior Captains until they rack up the hours.
