I also like the Rowi clamps because they come with a wood screw so you can screw the clamp into a tree or anything wooden, and realistically get wherever you want to
I have a Windtech too, mine is about 14 years old tho
Def seen its better days but is foolproof and works like a charm. The tightening screw that actually touches the stand will eventually break free and FUCK UP your stand tho
Thats why I recommend Rowi clamps for most clamping situations
