Which items should i cube next?

Right now, I have all of my lvl177 sair's equips with 2/3/4% dex. I'm satisfied with rare equips with 2/3% DEX, I still hesitate with epic equips with 3% DEX. Said equips are:

10w.att Canopus Glove
lvl100 Dual Blade Mask
lvl80 Shoes
Black Belt

All of these have 3% DEX in its secondary bonus. Should I recube these equips to get 6% DEX, or recube lvl90 Peacemaker(102w.att) which my Blindness is better in every way except w.att part(99w.att), or start cubing on Aran's equips which I'm not going to play any time soon.

In case this makes any different, I play in TMS, it's still pre-bb here. But I believe BB will hit in a few months.

1. Cube the item that gives the weakest potential buff currently and work from there.
2. Do not cube items you need to replace in the near future.
3. Do not waste cubes on 2 line items unless they have beastly base/scrolled stat

That about sums it up.

I base my cubing on how much the item can add with a single line vs. how much it currently adds.

Eg. Epic items with 3% stat can gain +3% if the first line is the stat you want. Items with no %stat can gain +3% too. Items that are level 70- and 2% can become +1% if you replace them with 71+ gear.

If anything does gain a rank (rare->epic->unique) while cubing, that bumps up its potentials so I adjust for that. But usually they don't.

1. Cube the item that gives the weakest potential buff currently and work from there.
2. Do not cube items you need to replace in the near future.
3. Do not waste cubes on 2 line items unless they have beastly base/scrolled stat

That about sums it up.

1. I already did that. Right now every equips, except non-potential'd Evan glasses, have 2/3/4% DEX. And that's what I aimed for.
2. All of them are my end-game equips.
3. It's too late for that. But then again, I only want one line to be super useful. It would take too much cash to aim for more than one line.

I wouldn't ask if all of them were still rare items. Getting %DEX in secondary line gives me "A few more cubes and it'll be in first line" feelings. But recube it also means risk losing who-knows-how-much-more cash to move %DEX to first line. I just don't know if recubing will worth it.
