I am completely happy with the Gorilla line of stands specially the silverback series.
I have the silverback Lite which is great if you have to pack in and out.
The Silverback has a bigger seat and platform than the lite so I have it in a perminant position at the lease.

Their climbing sticks are good as well I have a set of 3 x 3' which combined with the Silverback Lite only weigh 18lbs and is perfect for packing in and out.

On the perminant stand I have the stackin sticks which can get me up to 18' but they are not really suited for a pack in pack out day hunt.
