I also would probably restore the BB-8 hologram deleted scene after Holdo’s “Stick to your post and follow my orders,” or stick a Luke/Rey segment between the first Holdo scene and this deleted scene plus Rose’s introduction (which might help address another issue I had that I’ll talk about in a bit), but that’s mostly personal preference and a desire to keep as much Finn material as possible with Canto Bight being mostly gone.
…
Now, I do think a couple of the cutaways back to the fleet seem awkwardly short, particularly the one just after Luke’s first lesson, which I think would feel less choppy if it was placed immediately after the Maz scene. But I also think this is largely due to cutting Canto Bight down as much as you (and Hal) have, so it’s difficult to address this without throwing off basically everything else structurally. I think, as I said before, that restoring the BB-8 hologram deleted scene leading directly into Rose’s introduction, and placing a Luke/Rey island segment between Holdo’s first scene and it, could address this, though that means shifting every other fleet-to-Rey cutaway from then until at least Canto Bight, so I don’t know if it’s something you want to toy with for what’s really a very minor thing that might not even stand out on repeat viewings.
For what it’s worth, this did not stand out on a repeat viewing. I’d still like to see the Finn/BB-8 hologram scene restored, but it’s not essential and does require some FX work to get rid of the puppetry on BB-8, so it might not be worth it anyway.
