I don't think that pilots who have never flown the -700/900 should have their opinion counted as to whether we should fly both. Unless you've done it, you have nothing to base that opinion on except selfish financial or schedule motivation, and most 700 pilots will tell you they don't ever want to fly the 200 again!

How about this: get senior enough to bid it instead of trying to steal seniority/pay from the ones already on it?
