I really, really like my Summit Titan climbing treestand for hunting whitetails back in the midwest ... but you need a straight tree w/o limbs up to about 25ft of a certain diameter range for it to work.
For trees that are a smaller diameter, or have lots of limbs, or are not straight ... a hang-on stand with some climbing sticks are my next choice.
Let us know what trees you'll be setting up in and whether you'll be on private or public land.
