Wow those are some great looking clones. I know with clones you want to cut larger pieces than smaller, ones with the most bud sites or new growth. Definitely do the 45 degree angle like the others said. Put clones in water until you can dip them in cloning gel or powder and then put into cubes/pellets or at the very least soil.
If any have large leaves trim the leaves down, like each point of the leaf cut smaller and flat, it will look like a hand that's missing 2 of its knuckles rather than a fingered leaf, so they fit easier into you dome or the like, but you still have the leaves but a smaller version of them.
It looks like you've done most of that already, do you have a dome to put over the clones so they can have a nice warm moist environment to grow their roots?
With so many clones it really would be so cool to see you let them grow 6 weeks and then flip em to 12/12 and do a sea of green. :)
Whatever you do I'm sure will be great, I was so happy to see someone growing regular photoperiods strains...I've seen so many autos lately in my searches.
Happy growing.
