Ahh that's great B. I really do think you will see an increase in yield from the coco. Only thing I would say is they require more attention than soil, watering pretty much daily. Do you spend much time away from your plants? If so it may not be worth the switch..
I water my plants every other day, but I'm going to use bigger containers since I'm growing 2 plants now instead of 4. I think I'll also have to do some lsting so this thread is going to be very helpful.
