Q: 2. Does the bottom of the Center Column facilitate a Hook ?The pictures show what appears to be a cap on the bottom.

A: I have this tripod, and I do not have a hook. There is a plastic plug with a recessed thread. I could not determine the size, but it is significantly larger than 1/4x20. It might even be metric. The plastic plug is held in by a very tiny screw through the carbon tube. Even if I found a hook that fit I would hesitate to use too much weight.

Q: 3. Is it necessary to purchase any additional parts to mount a ballhead with the center column removed?

A: You can remove the center column on the Gitzo Mountaineer series without removing the mounting platform using it's "Ground Level" center column release feature. If you do it this way, you can keep the head on the tripod without dismounting it to remove most of the center column for ground-level photography.

Q: 10. When using RAID 10 (aka 1+0), what can be done with the fifth drive? I'm leaning towards two units; both RAID 10. First unit will be a main working unit and I'd like the fifth drive to be a hot-spare. Second unit will be my backup unit and I want the fifth drive to be available to copy certain critical files to (I'll then swap it out with a blank drive and take the filled drive to an offsite backup location). Over time, I'll keep trading the fifth drives when updating the offsite backup. Thank you. Side note: I've downloaded the various documentation from LaCie, but have not found any details on RAID 10 configurations.

A: Not certain that the hot spare can actively be used.While not invalid, using the second unit as backup seems very conservative. Also your backup unit should have more capacity than your primary to allow for file variations and history. You could use the 2nd version in Raid 0 configuration or use a simpler JBod enclosure.As for the offsite backup - a pair of simple Lacie Rugged drives that you alternate seem to be more cost effective and easier to handle.
