I have 4 gorilla silverbacks and plan to buy two more, 6 homemade stands (custum built for me by me) summit cobra climber (someone asked how good are they, they beat the loud API climbers by a long shot, easy to set up and climb with plus quiet as all get out) My two apis went to the ditch this spring hence my replacements with two new gorillas. Sorry if I offend anyone that is an API fanatic but in my opinion, they are the most worthless stand, the loudest stand, and the most dangerous stands on the market.
In preventing stand theft, I use a lot of heavy chain, masterlocks, and place my stands high. I have also used the removable steps for the first five up the tree making people who want to steal the stand work much harder......
