Belt only has 1 guaranteed slot, but I'm sure you could +4 it if you were willing to overmeld.
That was my conclusion as well.

It's not worth it.
Why does everyone forget about Sleep Ward potions? If you have 33 baseline resist with melds + HQ food, you'll be at 53 with a HQ Sleep Ward.
Over 50% reduction is nothing to scoff at. If you Purify the first sleep and pop a potion before the 2nd sleep hits you will spend a max of 10s slept over the next minute.
With 13 meldable pieces equipped (one hand wep + offhand) and 5 possible melds in each you could hypothetically reach 65 resist before food (unless there are caps on each item). Add on some food and pots and you're at 90% duration reduction. I'm not saying a sane person would actually fully overmeld a one slot item but I've seen min/maxers with fully melded Grade IV materia in everything. And that was before the price of materia plummetted.
So, what you're saying is, if a player forsakes all other benefits from materia/food/potions/purify and commits themselves entirely to countering 1 spell, they have a 60 second window? I'm not saying the potions (or sleep resist in general) is bad, but it does not justify the maximum duration of sleep.
PvP accessories are not meldable. Anyone who tries to use lv70 PvE crafts in high ranked arena will be crushed, sleep or no sleep.
Ill be more clear. ilvl 90 and Ilvl 70 pieces cap at +4 of one resist. Therefore you cannot stack resist past 28 with melds (yes forbidden melding included in belt). I made this post so people wouldnt have to waste marks. that is all. If you want to argue if it is better good or whatever make a new thread please.
I'm quite aware of how strong sleep is. The duration will likely be lowered in the coming patch. In general though the healer should be the only one concerned with stacking resist. You sacrifice almost nothing melding 10-20 resist on pieces that have lower stat caps (no chest/legs/weapon). Even without food you can exceed 1/3 reduction in duration for sleep/stun/slow etc after using a pot.
Run multiple suits. By the time you hit R30, you'll have enough for multiple i70 suits at least.
Or, depending on your class, there's probably a secondary stat that you don't care about, so instead of slotting for that, you could just overmeld in place of that.
Seriously though, at least as a tank, I always ran with a tank suit and a dps suit depending on the content. Not an issue.
