Forum:E-Hero Stratos Missing the Timing

Some guy tell me that stratos misses the timing when activates bottomless trap hole in response of its summon, thats because you've got to choose the effect and thats when it loses its timing, he said. I don't think so, because it's a mandatory effect. Who's right?..... Oh and about priority, if my oponent summons Zombie Master and declare he's going to activate his priority, he must pay the cost right?, discards the monster card and then can i chain book of moon or bottomless to make zombie master lose its effect?
