I just have a push-to GM-8, and a lot of times I'll reach down to loosen the clutch to go to another object and find them already "loose". I don't have to tighten mine much at all with C8's or an AT130. Some people have to really wrench them down. I don't know what the difference is. I suppose if you were going to leave the telescope alone you would want to tighten them down a good bit in case the wind came up.
