Think Quality of the contact, not the Quantity of the contact. A 50 khz band segment would have room for aprox 10 non interfering contacts.
Here is a quick general rule of thumb for non-overlapping channel spacing for the average $ radio or home brew.
CW-HF 2 kHz SSB-HF 5 kHz AM-HF 10 kHz FM-HF (3kdev), 20 kHz FM VHF (5kdev) Terrestrial 20 kHz FM VHF Satellite 25-30 kHz FM UHF Terrestrial 25 kHz FM UHF Satellite 50 kHz
You actual mileage will vary depending on the $$$$ of your system.

In the very narrow 2m band, 50 Khz would be more than enough. That's over 20 simultaneous SSB QSO's and dozens of simultanelus CW contacts.. I have Never heard an AMSAT even approach that kind of load.
50 Khz would be great in my opinion.
