Optimal slotting for an ST hold?

I've got myself a perma-dom (and no, I dont farm) that works fine, but I'm still looking to improve him. I already have an unbreakable constraint set in my glacier and so am looking at improving my single target hold, block of ice. At the moment it just got IOs in it and is a very regular part of my attack chain.

So my question is this, "How best to slot a single target hold if not with a purple set to optimise it fully?"

I dont need to worry about recharge at all and have a pretty decent acc bonus already, so one acc/? io/ho would cover it mose likely. If people want to see my build, ile post it up here if needed.

Currently my thinking for the slotting is:

1x acc/mezz HO
2x dam/mezz HO
1x Devastation - chance for hold
1x Damage IO
6th slot currently has an extra endrdx in it, but can either be used elsewhere or maybe another proc of some kind.

So what else can people suggest?

Tell anyone i told you this and i'll have to kill you but if you slot.

Ghost Widows Acc/Hold/Recharge
Essance of Curare Acc/Hold/Recharge
Neuronic Shutdown Acc/Hold/Recharge
Paralytic Acc/Hold/Recharge

It all adds up to 76% acc/hold/recharge (at lvl 50)
The rest you can add to taste like GW dmg proc and NS dmg proc or an End/hold / Acc/Recharge or whatever you fancy.

Remember i never told you this ... shhhhhhhh !

imo one of the best methods to 6 slot a ST hold is this:

3 Acc/Mez HOs
2 50 Rech IO

6th slot can be tailored accordingly, imo either an End Red 50 IO or a chance for hold. No holds do decent damage and even slotting a whole damage set on them still won't yield decent results overall. However, a chance for psi may be a good idea as with the huge duration can milk the ticking of the proc. The above slotting will mean you can basically stack and stack and stack those holds. I have almost exactly the above slotting on 1 of my doms and he can happily solo hold any AV/hero and even a GM with domi up.

Well seeing as its for a perma-dom build, recharge aint my thing, as its already on a 3 second recharge, so thats about as spammable as it gets. As for acc, I run tactics and have quite a lot of acc bonuses, so dont need as much acc.

My thinking now:

3x Dam/Mezz HOs
1x acc/end essence of cuarae
1x acc/end ghost widows embrace
1x chance for psi damage - ghost widows

Gives a decent amount of damage, great hold duration thats only very very slightly better with 3 Hold IOs, a decent amount of accuracy and end redux, a chance to do even more psi damage and a small run speed bonus to help his little legs get to the mobs before the brute does.

I think that might just be the slotting for me!

You will get more dmg from procs than just plain dmg IO's because the brawl index of a ST hold is quite low dmg wise.
