I recommend wiring them in series because if you buy a dual emitter it is wired this way. I believe this has something to do with the fact that wiring parallel will lower resistance, where series will raise it. It's possible weird things could happen with too low or high resistance but it seems to work for some. I guess it's just an "old school" thing that still works today and we still do it.
On the older xantech wired IR systems we used to install we wired them in parallel, but each emitter needed a 100 ohm resistor in line.
I dont know if wiring 10 emitters in series would work, but this is the standard when wiring a dual emitter.
Definitely agree that the MRF-300 is a better choice than the MRF-250
And to your last point, If an MRF can drive 10 emitters on one port I dont see why it wouldnt drive a blaster.
