I just picked up a new (to me) Leaf back which uses Firewire 800 for tethering. In shopping for a 4 meter 800 to 400 cable, I'm seeing cables ranging from Phase One for $125 to some rather skinny cables for $20. Is there any difference between the speed or reliability of these cables? Are there power issues I need to be concerned with? Also, what's the longest cable I should consider without worrying about losing power?
Thanks, John
