I've been using Jon's method for very large cuttings and for a whole bunch of cuttings I had left.  They were in borderline storage methods so I wasn't confident enough in their vitality to sell on Ebay.  I am selling some that were stored better.  Here's how I'm rooting the rest.  Some large ones were in large plastic bags.  This is a Costco rotisserie chicken bag.  Note the root at the bottom right:



These cuttings appear to be doing fine:





I put all the ones I had left from the fridge in perlite + small amounts of Napa Floor Dry and even less Peat Moss to try to root in the last 2 weeks.  There are lots of holes drilled in the bottom of these clear Sterlite containers.  I have 5 of these brewing.  Super cheap at Walmart.






I had some very large cuttings in this pot (~ 1.25" diameter by 20" tall) From Grasa's Adriatic.  I let them sit for ~ 4 weeks then submerged the pot in a larger pot full of water to float the perlite and scoop it off.  Even so I damaged a few roots.




The cuttings had plenty left, though.



I'm hoping to get fruit this year from this and at least 1 other.

I tried something similar with some large cutting. Maybe not on the same scale as yours but close enough.  



Just use a old GMC workout protein container filled it with dirt left it in my closet for a week and bam roots. The soil was damp enough for it to stick together, but not enough for water to squeeze out.

This was four years ago though. I really miss those cuttings. :(

Good idea with the submerging in water to make the perlite float.  I was worrying about how I was going to get my cuttings out of their cups without ripping off all the roots.

When it's time to float the cuttings out of the perlite I put the Sterlite containers in a larger container and run water through the Sterlite container (remember there are dozens of holes in the bottom).  If you plop the Sterlite container in a water filled container the perlite floats up quicky and tears the roots while the perlite scatters every where.

 

 

Then when the water's deep enough the perlite starts to float up and takes cuttings with it.  I scoop the perlite out into a waiting 15 gal pot to make room for more

 

 

 

When you have a cutting floating free (no longer stuck inside the Sterlite container)

 

you put your hand under the roots and lift it carefully out.  Hopefully this is what you see and put into a pot.

 

Eventually it gets easier

 

good method
