what type of knot do you use for the buckle for lowering the limbs down?
Ummm... not sure what you're asking... Aknot to lower a limb down? a block? More info needed for a correct response. Be safe!!
I like the anchor hitch but on really heavy you might need to cut it off. Lately I have been using splices on my rigging lines and love them so much cleaner, stronger, and qiucker.
3/4 usually won't go through the eye twice for an anchor hitch on those snap hooks. buntline holds well, and is easy to untie after it's been loaded
the proper term is snap hook. I refer to it as the buckle. the picture of one is on this link.

I always use a runnin bowline.
Even for big tops. I always tie a figure 8 on the tail.
Im kinda old fashion with my techniques.
Never had a problem yet.
