Flask to bloom times

[MuscleGirl'sHobby]

I've been pondering buying a flask and givng it a go this Summer. I've bought seedlings, and am not having any trouble getting them to grow like weeds. I think this would be a fun way to expand my collection over time.

I know the time to reach mature flowering size varies depending on species, but I was wondering if there were some basic guidlines. I'd be most likely looking at oncidium, cattleya, or zygopetalum, or vanda, but am also open to other species.

Can anyone point me in the right direction. Are there some species which mature much faster? Which ones are the tortises of the bunch?

All input greatly appreciated!
Thanks!
