Looking for tweets for buoyant.

Telofy OK, thanks for your opinions. :-) May 16, 2009
rolig I don't believe I've ever heard anything other than /ˈbɔɪənt/ (I grew up in the US). My only strong opinion is that one shouldn't pronounce this as spelled, with three syllables: /bu'ɔɪjənt/. May 15, 2009
bilby For me buoy is identical to boy - indeed, so is bhoy - and buoyant follows from that. I don't have a strong opinion, it's just how things are around here. May 15, 2009
Telofy I'm having a problem deciding which pronunciation I like better, /ˈbɔɪənt/ or /ˈbujənt/.
Does anyone have a strong opinion about that they'd like to share?
Thanks.
