I do belive you (or I) may have the wrong names in our heads, for me a "timber hitch" is the one where you take a wrap around the tree, backwards around the standing end, and take wraps around the rope using the rope pinching the tree to keep it tight
tying a timber hitch repeatedly to rig down logs would take forever, and do more rope wear (sliding across the bark each wrap)
unless you are magic, I know a timber hitch (7 wraps for me typically) takes me allot longer to tie than a running bowline
that daisy chain is about as fast as a bowline, but can be untied under load in about half a second by pulling the tail (I always tuck the tail back through the last loop incase it gets snagged it will pull the knot tight instead of loosening)
Hmmm. I wonder why they call it the "timber" hitch?
Nope. The only thing you have wrong is the need for 7 turns. Rope wear is non-existent. Quite frankly, you are really stretching for excuses to not use the knot with that lame theory.
Yes, you probably would take forever to use it, but your lack of skill with it isn't a problem that I have.
Try it with a few less wraps. I never use more than four, and seldom more than two. No, I've never dropped a log using that knot, either. Try it tied fast without worrying about whether it will actually hold. Just make sure that your wraps are ALWAYS made at least 50% back around the wood being hitched. Putting five wraps on without going around to the back side of the log is pointless and dangerous. Yes! Like any other knot, it can be done wrong.
Maybe try it when you don't need to rig at all, and see how few wraps it takes to hold reliably.
I also generally use the timber hitch to set my portawrap, although I usually use "slipped" wraps, so that the tail can be yanked and release the whole thing. Particularly heavy rigging on a large diameter tree, I'll use a stilson hitch. Same for very short chunks coming out of the tree, on account of that's a hitch that just doesn't fail.
Your daisy chain looks like it will take up too much tail, and leave a dangly knot hanging down to be cut carelessly, or it will be annoying at a minimum to work around. If you don't mind doing that, I don't mind that you do it either.
