Default double hook or single hook, AK FCG


I'm at the final step buying an AK kit for my NDS receiver, and I still haven't decided on a single hook or double hook FCG/trigger. Going for the G2 kit, both are available, same price, and I just can't find persuasive information one way or another. So as a last ditch hail-mary, can someone persuade me? From what I've read, either will work on the NDS 1/3 receivers, correct?

It all seems like personal preference. I'll be building it myself, if it makes any difference. I'd like to get my check off today if possible, any quick thoughts?

What is your reciever cut for? I would just go with that? I personally liek DH. But if my reciever was cut for SH I would just stick with that. Then again it would take you 10 min at most to cut a new slot for a DH.

All of the ones I've had experience with have been DH so this is not from personal experience but most of the reading I've done mentions "trigger slap" (the trigger slapping your finger as the hook re-catches the hammer after firing) with the SH and it not being evident with DH.

I've done all mine with single hook.

However, Bladewurk learned that the double hook is actually better if you want a better trigger setup. You only cut the second slot as long as it needs to be for the hammer to engage, which means you've basically eliminated the issue of overtravel.

That having been said, if cutting on your receiver scares you, go single hook.

Yup. I cut the slot open on a single hook ewbanks receiver I had and works well.

I will vote for a donkey-sex maniac if he's pro-gun.

As another point of reference, the PSL has a single hook fire control group that has a little ridge on the very edge of the hammer. The little hook on the trigger slides across the flat portion of the hammer until it rests upon the ridge on the edge of the hammer. It takes a harder pull to release it. This FCG doesn't have any finger slap.
The Tapco G2 FCG single hook doesn't have any finger slap.

Default Which FCG?

Here's the answer I got from NDS:
The trigger slot dimension is basically the same on the NDS-3, NDS-65,
NDS-7, and NDS-8 receivers. These receivers have a single hook slot. The
slot is dimensioned for the Century trigger. The slot allows some overtravel
with the TAPCO G2 trigger but we have found that general function is okay.
The Arsenal/KVAR trigger and Century trigger have less overtravel than does
the G2 trigger, and we think the Arsenal/KVAR fire control set will provide
a stronger reset.

The NDS-1, NDS-1P, NDS-1ROM, NDS-M92, NDS-2, NDS-2SF, and NDS-2T receivers
have basically the same trigger slot, which is shorter in length than for
the receivers listed in the first paragraph. The receivers have a single
hook slot. The triggers you list below will have about the same overtravel
in these receivers. We think the Arsenal/KVAR FCG will provide a stronger
reset than the TAPCO G2 FCG.

The NDS-4, NDS-5, NDS-9 and NDS-Y556 receivers have double hook slots. Any
of the triggers you list will work with these receivers, as will double hook
