The green tips of sion material often fail as flat grafts, but for some reason they have a high success rate as V grafts.
I learned this in a Thai video of a full time grafter churning out dozens of grafts per hour. He had rhythm pumping out flat grafts until he got to the green tips and then he V grafted the last piece.
I figured that there was a reason if they were doing it commercially. I think that it's got something to do with the increased grafting surface area.
I've used it this year with 100% success.

PS. I use grafting tape to hold the sion just tight enough for 8 days.

I think all commercial seller will use flat graft, as those will save the stem used, what they need is just one "growing point" , usually they use around 1 cm of the stem per graft, if V graft will take around 2 to 3 cm.
Only for the last one they will use V graft, because for flat graft they need the grafting tape to press the stem from top, which can not be done on the last one as the growing point is at the top of the stem, then they will use V graft for this.
