brackishfigger,
I've just discovered this thread. First let me tell you - what an wonderful job. Overwhelming!
Secondly, reading your comments and seeing the pictures, i realized why some of my grafting experiences with fig trees, a couple of years ago, failed miserably. This year i successfully grafted 5 different varieties to an adult tree, but i learned the hard way - whish i knew this thread before.
The almost essential use of parafilm, that i began using recently with all my fruit trees grafts, and the importance of protecting and rewrapping the grafts in fig trees (specially the chip grafts) should be highlighted in red. I realized it was the main reason to my failed chip grafts in the past.
Also, Axier's invaluable work ( http://figs4funforum.websitetoolbox.com/post/english-translation-of-axiers-how-to-graft-an-adult-fig-tree-4504717) was the reason many of us started grafting adult trees with multiple varieties, but i wish it was more clear from the start, the importance of protecting the grafts of fig trees for longer than usual, to achieve success.
Also, i was amazed to find that whip and tongue grafts, done at bud break, where so successful when i tried them this year on an impulse (all 5 that i did this season took without problems), when it was not mentioned in his text, where he recommends the chip graft as the best. You seem to have identical results with that type of graft.
From what i can take from my own experience this year, the whip and tongue graft is even more successful than chip grafts - more complicated to do correctly, of course, so practice and experience is a must.
They should both be well protected for a long period, but the chip graft is much more sensitive when parafilm is removed or simply cracked - they start to dry up real quick which doesn't seem to happen with whip and tongue - probably because there is a larger reserve of nutrients in the bigger cutting piece we use for this type of graft.
Your own work seems to confirm my conclusions. Also, when the season advances its more difficult to avoid the drying up of the grafts, specially the chip grafts.
I've successfully grafted in May with whip and tongue, but additionally to the parafilm i enclosed the whole graft in a brown paper bag until it took and had some leafs in it.
This season i've tried chip grafting in late August, with fresh cuttings (thanks, Francisco). I'm curious on the outcome. In a few weeks i will try to post the results.
Thanks again for the wonderful opportunity to learn.

Parafilm - http://www.amazon.com/Parafilm%C2%AE-Grafting-Tape-Genuine-Clear/dp/B0085OFNVE/ref=sr_1_3?s=industrial&ie=UTF8&qid=1441722946&sr=1-3&keywords=parafilm
It protects, letting the graft breath while keeping the moisture inside and the young buds break it without any problems - worth every penny...
