Potential and cubing question

Now I am trying to get some decent range.
I have a Unique ATT+10%, DEX+7% Gun, a Unique ATT+15%, DMG+6% Emblem, and an Epic secondary weapon.
All my other armors and accessories are Epic with at least 6% DEX.
What shall I do next? Shall I continue to reroll my gun, or shall I keep my gun until next Miracle time, and focus on the Emblem now?
If I want a Unique secondary weapon, shall I use Cubes to reroll it and expect it to tier up, or shall I buy many 30% unique potential scrolls? In my server, the price of 1 unique 30% scroll = 2 red cubes.
Thank you very much!
=====================EDIT======================
I found a cheap Unique 30% in Auction House.
It SUCCEEDED! All of the Unique 30%s I bought were successful!
However I used 17 cubes to get ATT lines, and it is still not primary.
Now I get a DEX+9%, ATT+6% secondary weapon.
I have only 2 cubes left, so I am currently satisfied and will keep it until I have many more.
