I mean, it's cool and convenient, but just not practical. $200 for a system to hang sticks or ladder stands, I'll pass. All you need is a bit of redneck ingenuity, and you can get it done.
It's a cool idea for someone who's not able to get any help to put up stands, cheaper then your deductible for a hospital visit...
like Greg said, a couple guys and a little forethought and you're golden and have money still in your pocket....
