Grafting bands and the Durability vs Restriction

I have totally replaced the traditional elastic band method in favor of these green colored cattle castrators (shown in my hand) for quite some time. The squeeze on my finger tip feels tight but all my grafting this has never been too constrictive for the living wood. The loose green band was just released from the one inch diameter metal after about a year that way, so the rate of stretch seems about right. 

Here again a one inch diameter tree/play project shows the release rate adequate enough, and still firm enough in spite of weather, temperature fluctuations etc. it's still tight. This had been for a pear cleft graft with the band rolled downwards for inspection.

I know two bands are needed for adequate standing strength and make coverage of what one elastic band accomplishes. One big advantage of green banding, at least in my eye, is that it gives ample visual inspection time to make sure the cambium is aligned as close as it can. The buddy tape, parafilm, or what's used for rainproofing, can be applied over and restriction of the green bands are still not an issue.

While switching over to this new thing I often wonder if the traditional elastics release enough over time and age, or if at all -being covered with the yellow Doc Farwell?

I think I've told you, I've seen those bands before as part of a mouse trap:

I'm all in favor of innovation, but I don't really see any tangible advantage to these.

The green band method being easier to inspect alignment will eliminate any need for the last cut that can be such a hazard in whip in tongue. Put that box knife blade in a nice anvil cutting device and eliminate the sliding knife process altogether.

These kinds of choppers give the more complex grafting machines a run for the money and give a great long sloping cut for green banding to take a good effect. I think I can still get these choppers for very cheap.

That looks interesting.  There are so many good options now.

I use strips cut from plastic zip lock freezer bags.  They have a learning curve, and take a bit of time, but I like their wide area of pressure on the graft.  They also don't degrade automatically, so can be constrictive if not removed. Still, I've never list a graft doing that.  Also, even if there is constriction, the graft seems to survive and grow.  I've discovered a few in the Spring, a year later, and removed them then.

I do see the advantage of the rubber bands, especially if they are self-removing.
