Heyas,
I would point out that bringing the 175 to the mainline (buh bye Republic et al), we also pave the way for the 195.
Like the DC-9-10/30/40/50, 319/320, 757-200/300 etc etc, and others, you can have a common crew fly the right sized aircraft for the market, and you can fly as many of them as you want. Seems to make good economic sense instead of drawing an arbitrary line.
Slow has a lot of nerve, laying this on guys who just want a quick upgrade. Reminds me of some old RB guys I flew: "we have guys on furlough?"...they have their ladders on a high speed retraction mechanism, and sound like Pavarotti warming up: "Me Me Me ME ME!"
