I think that the issue of standard BH or crossbow BH is dependent a good deal on the crossbow they'll be shot from.

I've seen this type question asked before, most say it does not matter........but....

I bought a couple packs of Spitfire standard 1 3/4 cut BHs. LOL! ! !.......they fly out of my Scorpyd 165 like ones you'd see on the Roadrunner & Wily Coyote toon....which means they'll fly off at strange angles the instant one or 2 of the blades deploy in flight........so not so good.

Went and bought some Spitfrire Max Crossbow BHs, problem solved, they stay closed in flight & are highly accurate. The crossbow ones are also 1 3/4" cut. They have a much stiffer spring to hold them closed though & are 125 gr. where as the standards were 100 gr. ones.

I'm pretty sure my Scorpyd isn't the only one this is true for. If you've a fast Xbow of 380 fps or higher, I'd suggest buying the crossbow BHs. If for no other reason than peace of mind.
