You should always wait for an event before invoking (reinvocation or element invokes if you need a specific element only). I usually prefer single reinvocation events than mega reinvokes because you can decide to keep or reinvoke for each spirit unlike mega reinvocations where you might be forced to keep spirits that are useless just because you get one or two good ones (of course you might get more).

Although it depends on how much you are willing to gamble, Mega has low risk but single invoke has higher reward IMO.
