Well... I do a lot of night walks but not in gator infested areas
I find I like a long throw light for "spotting" and it looks like you may be after the same. The G2 is a great light but not really suited to spotting - it is more of a general purpose light. I carry one as back up for my main trail-following light an A2.
For spotting I perfer either a SF M3T ( very costly ) or a SL TL-3 ( great bang for the buck ). From your list either of the Wolf-eyes would be a better choice than the G2. My only concern ( not having any experience with Wolf-eyes but tons with SF ) is relability. Yes- very little can go wrong with a simple direct drive incan but when you are up to you knees in gators - that is not the time for anything to go wrong. Wolf-eyes get a lot of good press around here so a search will give you a sense for them but for me SF ( leaving the U2 out ) is the benchmark for relability.
If you look around you could probably find a TL-3 and Lion setup for a resaonble price - that would be the way I would choose. Even without a Lion setup the TL-3 is not that bad on batteries - if you keep it to its intended purpose, short runs of spotting, not constant on.
Good luck and many safe walks.
