Sangue Dolce Grafting vs Rooting

As everyone warned Sangue Dolce (from Wills) is very hard to root. The one cutting I put in a fig pop rotted quickly. On the positive side it seems like it is also very easy to graft. I cut up one small cutting into three cleft grafts on some Brown Turkey rootstock back on January 7th. Two of the three are already doing well and the third is still showing green.
