Plan: Two off camera flashes (one ETTL and another probably manual one) + YN622C triggers.
Option I: YN568EX (key) + Nissin Di 466 (highlight) / YN 560II (highlight) + YN622C
Option II: Nissin Di622 II (Key) + Nissin Di 466 (highlight) / YN 560II (highlight) + YN622C
Doubt: YN568EX does seem to have GN of 39 (actual test results) as opposed to GN of 58 mentioned.
Nissin Di622II is more than 44, but does not have HSS. I may need HSS at times.
Am I going the right way? Is there any other similar permutation / combination which will give max light, through ETTL, at least cost. My plan is to get a high power fully loaded flash at first, and then add the triggers and second flash in second purchase. And thats where the confusion is, is YN568EX is powerful enough for most occasions.
I've to purchase it in this week itself, so please flow-in your suggestions.
PS: I'm not interested in manual set-up.
