I would rather just use the wma as I can't hear any difference. I still use the 32 bit version of Biab, if I need to use a 64bit plugin I just use JBridge in it as it works fine, I can't really see the purpose of the 64bit version. If I need to use a DAW I always choose PowerTracks for any editing I can't do in Biab, but hey that's just me.
