I think your package is a good one. If you want a bullet proof reg, stick with the Odin. It will serve you forever and won't go out of "style". If your going to a Nitrox computer only costs a few more bucks, go for it. I've only been diving for 28 years and haven't gone nitrox yet. Haven't found a need. But you never know. You may have a reason to spend twice as much on fills for no realistic gain. Let 'er rip!
