RE: Hindsight
Though I don't own one so I cannot comment on long term use, I have shot one fairly recently at a local shop. I agree that it is a bit "different" to shoot at first, but after shooting a couple dozen arrows it felt very natural and very comfortable to shoot. I can see it's advantages and disadvantages for different situations. I personally, after my short experience with it, would like to try it out for a season or two.
To the comment about the thick crosshairs - I think pictures you see in magazines are a bit misleading, if you can shoot with both eyes open you probably wouldn't be bothered by the crosshairs as they aren't very thick from left to right when looking through the sight, but rather deep from front to back.
Good luck this season with whatever you choose.
