Optimizing the counters, dissolve??

Currently running 7. Mana drain, counterspell, negate, stifle, forbid, dissolve and render silent. Deck is esper. "Force of will!" Yes, i know, im waiting for a judge version, that will take render silents place. My question: should disallow replace dissolve? Or should it be swan song? Im thinking disallow, but i also really like shadow of doubt (not a counter i know). What would u do?
