I just bought some Muddy sticks this week, but brought them back the next day without even putting them on a tree.
Very well made, and the design is good, but just too bulky for me. And, at 2.5 pounds they are the same weight as Lone Wolf sticks and only just over half as long. In other words I can get up much further with the LW steps for the same weight.
If/when I do get a set of sticks, pretty sure they'll be LW's.
If I was going to just set them and be able to leave them in the woods, they would be a great choice....but for backpacking in and out every time....I plan to just continue to use my woodpecker drill and bolts. Much easier to pack, lighter, and after the first time up drilling, you only have to drop them in the holes....quick and easy!
