I sugest this: For the system partision keep FFS... yes it's slower and validation is a pain when it has to BUT in my oppinion it's safer and have better recovery tools. Just keep it small and you should be safe. For the rest use SFS, it's fast and it's free.
For seing drives larger than 4/8GB you need kick3.1 and a newer scsi.device (such as found in WB3.9) I belive.
