Use very little down haul. Set boom at bottom of the cut out. Down haul and adjust boom as needed.
I also prefer the rubber shims over the RDM boom inserts. I have newer Chinook carbon booms. The RDM insert works well but not as good as the rubber shims. I haven't has a mast show any wear since I started with the rubber shims...

The Streamlined Dyneema RDM boom head will give you all kinds of room for your hands, plus a bit more room for that batten. Make sure you get one with the correct shims for your boom. Also, be sure to bench-assemble the head before you install it on the boom because sometimes the holes for the mounting screws are poorly located. (It really pisses me off to buy or recommend something with such poor quality control, but for me the benefits are worth it.)

The worst mast sleeve + boom head combination that I ever had for rigging is my 2015(?) Aerotech Phantom 6.8 and my old fiberspar boom clamp. The sail has a number of features that make the mast sleeve area tough to work with, the most egregious being the protruding batten end in the middle of the cutout area. >

Yes, totally agree!!
And the Kona sails (which I really like in general) have this same batten-end that extends right into the boom cut-out area (and this specific feature, I don't like).

Anyway, I don't have a big issue rigging them... cause I do the same as the others have said -
Minimal downhaul... attach boom... outhaul fully (which pulls the batten-end away a little bit)... downhaul fully (pay attention to the batten end, as it moves past the boom clamp)... fine tune outhaul and downhaul.

If you otherwise like the sail, I would think you could take it to a sail maker and have them remove the screw adjuster from the leech end of the batten and install an old-school ladder lock or cam lock adjuster with a webbing strap. This way you could easily slide the batten back a few inches so it's out of the way when installing the boom and then just tighten the batten after the boom is on. It wouldn't really cost you any rigging time since you have to go to the back of the boom anyway to hook up the outhaul.

Good idea sm!
Sounds like a workable solution to me, for this issue... if the other rigging tips don't work well enough.
