I would say it like this:
- Argument: lack of experience in micing drums. If this is your drum session (including live gigs) between numbers 0-50, mic the kit. It doesn't hurt to learn. Experiment with mic position, but beware of the proximity effect.
- Argument: triggers. You don't need triggers for sample replacement, you can do it from the mic signals too if you have miced the drums well
- Argument: "I don't have high quality mics". You don't need hi-quality mics, except maybe for the kick you need something that can withstand good amount of soundpressure, but in general almost any dynamic mic will do for drums. I have miced the whole kit with SM57's and a kick with D112 for many many times
