G41 info on Cummins' new website

[Asturias_in_Ohio]

On the new Cummins website, they mention that due to breakage issues on the G41, they’ve switched entirely to whip and tongue grafting on that rootstock which has entirely eliminated occurrences of breakage at the graft union in their nursery. Has anyone done a whip and tongue graft on G41 and still had it break after having planted it out?

There is some discussion about budded vs grafted trees on Geneva rootstocks and the effect on graft union strength in this thread.

Major problem with Geneva rootstocks?

After a thunderstorm with a 50mph wind gust, I have now lost all but one of my initial orchard planting 6yrs ago. Last night, two trees were snapped at the grafts, clear, bright, undiseased wood, moderate fruit load, looked like I had chainsawed them at the graft union. In the last 3yrs., the lost trees were on a mix of G41, G202, G935. Trees on b118 and m7 have not failed and carry similar fruit loads. 11 out 12, 6yr trees, 5 this year alone. Has any one else had this kind of breakage? Is there…

@mroot With the exception of one comment about someone doing a cleft graft, it would seem all other comments refer to bud-grafted trees, hence me asking if anyone had specifically had G41 trees that were grafted via whip and tongue. If it made a huge difference, I would certainly consider the G41 a lot more.
