Shoot a heavy, heavy arrow, or just a heavy arrow?
45#@28" draw 29.5 Kodiak Hunter (RH). Shoots 2117's cut 32" w/175gr up front real nice. Shoots the same with 2018's cut 31" w/145 up front. Bare shafts hit with fletched, bare shaft nock a little high, and to the left. The bow is a whitetail rig, and of course lots of practice playing around.
I know the 2117's will probably give more reliable penetration, but the 2018's should shoot flatter.

Either one will work well for deer. I think I would go with the 2018's. Faster and I like the smaller diemeter
I shoot 2018's out of my 52# LB, fly great and had a pass thru shot this year.
I shoot a Turkey Creek Longbow
43 # @ 29" 63AMO, I use Axis 500 with 125 G stinger Broadhead upfront, 5 in. feathers three fletch 428 G total arrow weight 189 fps.
They penetrate into a Block Target eight to 10 in. I find the Axis arrows are very high penetrating, very true to flight. Didn't have any trouble tuning the arrow to the bow.
