But in my opinion also form of this (heavily ported) spool can cause noise as well.
I've seen this as well. Some of my DIYs will be slightly out of balance in that when flicked on free spool the spool will rock side to side before coming to a rest. Not a big deal or anything but it is a tell tail sign of unequal mass distribution in the spool. My Haibo 50 stock spool also do this and look just like the Ray's DIY spools so there is that. Again this is more of a quirk from these spools rather than a performance issue but I do believe it contributes to the noise of the spool. The tolerances of the Air Brake like mechanism are pretty loose too and allow the inductor to rattle around. I think the tolerances on these spools are what makes them noisy. My Pixy DIY is out of balance and makes a metalic rattling/ringing sound when casting but despite being my loudest DIY it is easily the best casting DIY I have with the ability to absolutely bomb baits or stop them dead I their tracks depending on the mag dial setting. That spool has a ton of range to the mag dial in ways my others don't.
