368 grains on a 72# now is very light, you're flirting with the 5 grain per pound rule of thumb for minimum safe arrow weight to not blow up your bow.
By comparison, I shoot a 450 grain arrow to 100 yards routinely, haven't gone further only because my property isn't big enough. 28.5" draw, pse mach 1, 332ibo. It made 72# with the last set of strings, only making 68.8 with this set and the ata is shorter with this set (haven't been able to figure that out).
I still have quite a bit of room before my fletching will contact the site housing, but I'm also not shooting 3d courses for score. Ultimately, it's your arrow, but you do owe it to yourself to try the free trial of pinwheel so you can find the option you like best. Pinwheel software also includes a ballistic function that you can learn a lot from.
