What about the noise level though? I've heard that they are kind of loud. I have a CPR bakpak, which I'm not too impressed with, and I was thinking about getting a Remora. My bakpak used to be pretty loud, but I did the bioball mod on the maxijet and it quieted it down to a whisper. I really like that, but I'm still not too happy with the lack of skimmate it's pulling. All I seem to get is light green water. Can someone please comment on the noise level of their Remora?
