Some advice, thundermug, if I may....
I love my Cobra, I' ve tried API' s, Summit' s, Loggy' s, etc, the Summit has them all beat.
One thing to check for, in the tubes where the cable slides into, mine had a few sharp edges in there that ripped the black plastic off the cables over time, might want to take a look and hit it with a file.
If the black plastic does come off, they sell something at hardware stores that' s a spray, and will coat those cables like new, it' s used for color coating tool handles, etc.
The leveling feature is nice, and perectly safe if you' re in a harness, but try it a few times on your backyard tree a foot or two up before trying it at 25' . It' s a little tricky at first.
Oh yeah, get the padded straps, and the bag for odds and ends that Summit sells, those are nice.
