Chancing league items in standard

hey there.
Need some advice.

Im sitting on a vast amount of chancing bases, collected over the last 2 or 3 temp leagues.
All in all approx 8 to 10 full tabs of Leather Belts, Agates, Citruines, Moonstones and some more certain types of TSR.
I also have the required chance orbs as well as the currency to open up enough Zana maps.

Question is: If you are in my stead, would you rather sell the bases (i know the guys that buy them at good rates) or chance them myself ?

advice appreciated, thanks.

do you want a chance to get the unique or do you need currency? its that simple.
