I've been shooting the 3-blade vented 100 grains for 10 years now. I do have non-vented and was not able to notice any difference in noise, I think my vanes make more noise than the majority of broadheads on the market. I've been very satisfied with the VPAs, I have tried other heads now and again but always found myself going back to the VPAs. The one thing I actually like about the VPA heads is you can put in extra time with flat stones and get the blades as sharp as you want. I feel sharpness of the blades is a a close second to only shot placement and I spend a fair amount of time practicing shooting, so why not put time in with the sharp end of the stick.

 

The gentleman that owns Stay Sharp did a video on head noises. Pretty much provided it’s all in our heads.

 

I have killed deer with both vented and non vented. I think the vented might be slightly louder. But I couldnt swear to it because like allankuz I think the fletching makes more noise.
Ill say this though. The non vented are just about indestructible. And like allankuz I think they are easy to get sharp. I can shave hair after the flat stones if I finish them off with a ceramic stick or a leather strop. Also the Stay Sharp 344 that changes the angle from combined 60 degree to 44 degree does work. It takes some time but they are really at another level. Im not sure its necessary though.

 

Update. Picked up some 125 solids the other day.
Shooting the VPA 125 solids with the V100s, I can’t tell the difference in noise.
Just me, but I think we tend to overthink the inconsequential.

 

I've shot the 100 grain solids for a while now, and they have proved to be great heads. The 100 grain vented had a slight amount of noise for me, but it was very slight.
