This year I started 18 varieties of figs and 14 behaved as they should.  Grew roots then leaves, went to a 4 inch pot, then to a quart pot and are hardening off.
A few have been problematic.
They are Drap d'Or, Saint Jean FN, Peter's Honey FN and Atreano FN

Drap started then stalled.
Saint Jean FN grew leaves but no roots
Peter's Honey FN just sit there but may have start a root today and
Atreano FN is also not doing much.

The ones (4) that haven't grown roots started to wilt so I tossed them on the cutting bench.
I hope that the frequent misting will perk them up or finish them off.
It where we do hard wood cuttings.

Anyone else had issues with these?  I think I should squeeze one plant of each but they were a bit more work,

I've experienced the same issues.  I don't know of a fix, but consistent humidity seems to be the best practice for me.  Even still, you get cuttings that just don't want to behave.

Patience pays sometimes. I have a CDDG that put out a leaf but no root in February. I kept it in a humidity bin, and it just started roots and a new leaf.

yupe. no roots means they need humidity or the leaves will wilt and drop. 

I often get stalling for winter-rooted cuttings.  They start out well with roots and leaves and then just stop growing.  Over time, the old leaves start looking kind of raggedy.  However, once they get hardened off to the outdoor sun and the weather warms up they usually start making new leaves and are fine.
