[PlanetCCRMA] New user; FC3 or FC4?

[Paquita]

Hi,

I'm new to audio under linux, and about to try Planet CCRMA. I read a bit,
but currently it's not clear to me which Fedora Core version I should
install : is Planet CCRMA already ready for FC4? Or am I better off
staying with FC3 right now?

I'd rather have a stable system, and I doubt I will need anything really
cutting edge. My goal is to do multitrack recording using an M-Audio Duo
USB interface.

Thanks,
paquita
