I think the "I only can afford one" approach is flawed.
As an example: I can buy one lone wolf hand climber for around $350 or I can buy:
one hang on treestand from Menards for about $60 (bigger comfortable model opposed to the $30 small hang on) and 4 climbing sticks for $15 a piece which makes $120 total. They also had a climbing treestand which looked decent and was $189 normally but $129 on closeout. Added up to $249. Now they had a 18 ft ladder stand that was a little flimsy but light for $50 a piece.
I bought two of them and to make them even better and more stable, just cut 2-3 ft off the lowest ladder section to get 16 or 15ft ladder stands.
I am right now at the same price as I am with buying a lone wolf climber. I love my lone wolf climber, my lone wolf hang on, 3 double bull blinds and ladder stands but more stands buy you more versatility.
Example: Place the ladder stands permanently and also the hang on stand if you wish and leave your climber in reserve. If you hunt from your ladder stands/ fixed position stand, often you will see a deer pattern developing close to the ladder stands but not close enough to shoot. The deer may know that there is a ladder stand or they use the trail over which you set up at different times when there is no hunting possible.
But if you see deer from your ladder stands, then you can surprise them when the weather is right with taking your climber and set up where they come along at the weather/wind pattern you observed them coming out.
Ladder stands are great and easy to hunt out of and they are also great scouting stands....
