4 fletch will be even louder. Cody Greenwood found that the helical configuration is the culprit for noise. This can be corrected with a simple offset. However adding a vane no matter the offset or helical will always be noisier.I'm currently having issues (whistling noise, but great groups) with an aggressive helical on a micro diameter shaft: https://www.rokslide.com/forums/threads/arrow-noise-w-field-tips.217927/
Most likely culprit right now is the vane configuration (air getting between the base of the vane and shaft). If I can't figure this out in the next two weeks, my next choice would be a four fletch with Bohning Heat vanes, straight clamp, and a 2 degree offset.
I haven't noticed my 4F being louder than any 3F. I set em straight with a right wing clamp. My pepsi test people say they're noticeably quieter than any 3's.4 fletch will be even louder.

I'm just going off of the tests performed by Kyle at DC and John Stallone's test at AAE. Both of them reported the loudest 3 fletch configs were still quieter than the quietest 4s. I think the benefits of 4 fletch outweigh 3s anyway. The testing done on animals reaction is subjective at best. Alot of killers out there getting it done with 4 fletch. I always say it's better to have a poop your pants shaft that's a little louder, then some tiny vane that isn't going to correct when the bow is torqued.I haven't noticed my 4F being louder than any 3F.

This is why I think the noise issue is ridiculous. What people hear and what high tech machines produce can be totally different. Interesting that the TACs sound loud. I thought those were supposed to be very quiet.When we have league, we'll stand parallel to the targets about 20-25 yards away (10-15' elevated above) sometimes and get to listen to the arrows coming screaming down range. I can always tell who is shooting 3 blazers or the TACS. I wonder how they tested the configurations. If you have 3 loud vanes, and add another it will obviously be louder. I find it hard to believe 3 blazers is quieter than 4 Gas pro or Pine Ridge Nitro 2.2.
I'll need to go watch this video.
Regardless I agree. Forgiveness is key.
I think it depends on your arrow set up. Lot of these guys are shooting 310fps+. I noticed even shooting them sub 290fps they had a hiss. Mostly the Drivers.This is why I think the noise issue is ridiculous. What people hear and what high tech machines produce can be totally different. Interesting that the TACs sound loud.

Probably no one cares anymore (a month later), but just in case, I'll share this table put together for other purposes showing the actual angle you get when you use any available jig to fletch skinny arrows at a supposedly 3 degree angle. The takeaway is that because of the way these jigs handle skinny shafts, all of them will put less than 3 degrees of angle on any arrow with a less than "standard" diameter (~0.300") shaft. That said, a 2 degree helical on a 0.200" outer diameter arrow will behave almost exactly like a 3 degree helical on a standard diameter shaft in terms of rotations per yard and will be within 10% of the same drag.
If you ever did put a true 3 degree fletch angle on a nano diameter shaft it would behave more like a 4.5 degree helical would on a standard diameter shaft (not shown in this table, happy to geek out if interested). By most internet "studies", that would be overkill.
