HAs anyone used the GamePlan Gear Spot-N-Stalk Quiver Pack? Seems like it would be a good fit for stalking.

I had one for a little while.  It was nicely made and handy being able to rotate the pack forward to access the compartments, but after a while I decided I didn't like having all the weight on one shoulder (its sized to encourage carrying a decent amount of gear) so I traded it for a regular pack and now depending on what kinda hunt/duration I will be facing I either go with my backpack or just my Bowmate Elite side quiver , but 9/10 of the time I only bring what will fit in the compartment on my Bowmate and clothing pockets.  You can attach a quiver to the Gameplan and it is cool feature.  I would say its a piece of gear you have to try to see if you like the one strap concept.

I had one, very good qaulity. It's just too hot down here for one. Having the pocket side wrapping around my mid section made me very hot.

I have one as well and really like it.  A couple quality issues with the zippers though.  Most of my hunts require a very short walk so I really don't need to carry too much with me.  So I use a fanny pack most of the time.
