You could use Placidus. The article is mostly from Bonatti and Masha'allah. I'm not entirely convinced that Masha'allah was using whole sign exclusively, though I know he used them for most things, and I know Bonatti used Alchabitius mostly, and whole sign for some things, Lilly I'm pretty sure used Regiomontanus for everything, but use Placidus if it suits you. If it works for you, then stick with it.
It's what everyone else did, after all
But you might want to take a look at the whole sign as well as the division - it's easy enough to do. My whole sign nodes are even more grim than my quadrant ones - but they're both true.
Here's the thing - unless you have a miraculous stroke of luck, you're going to find little in the literature, be it traditional or modern, that describes your aspect or planet or node placement to the proverbial 'T'. You've got a planet or planets conjunct a node if I remember right, so that's going to complicate things, too.
Use the delineations as a base to build on.
