the 2" groups at 70 with an untuned bow ... hopefully this will convince people that it's okay to stop chasing accuracy with their wallets - I mean buy whatever makes you happy, but realize that it will not be the holy grail of accuracy ... and how you tie your nock points don't matter either.
As far as single vs double bevel, I think (hope) most of us who choose single bevel do it for the benefits upon impact - as negligible as they are - in that "if" they hit heavy bone the chances for continued penetration are a skosh better - just a skosh. But yeah - a fixed blade and field point that hit together at 80 yards is by chance, not by quality of product or tuning. Much agreed. I do recall a video a few months ago from Brandon McDonald who was stating that single bevels increased accuracy. As convincing as he may appear to be, i ain't buying it.
The data collected on vane noise left me with more questions than it did to provide me an answer. But I wasn't asking that question to begin with. The author of the article emphasized that portion of the research, stating it was important to him because he states the hiss of the arrow continues after the sound of the bow dissipates. That sounds sensible. But at what point is the animal detecting this, and does it matter? My personal experiences lead me to believe that I could have someone behind me clanging pots together when the bow releases, and it wont change a thing at my hunting distances. The second question it left me with was, the spread in decibels was roughly 9 from the quietest to the loudest- how detectable is a difference of 9 decibels in the 50 - 60 decibel range? And be it 50 decibels or a 100 decibels a noise is noise and it has the animals attention, so does any difference noise level matter? I say it doesn't.
The drag coefficient and wind drift data was something I found interesting. Not enough to change my mind on anything, but the numbers were interesting. Drift was not adequately explained. Was it measuring a group of arrows in a particular configuration, where the entire group had drifted from the POI of the control? If that's the case, then drift is insignificant since it can be corrected with a sight adjustment. The fact that this portion used an out of tune setup though makes it irrelevant and inconclusive in it's results.
I'm curious now how many Iron Will wide single bevels will pop up in the classifieds though, and for likely-to-be unsensible reasons. At my hunting distances at least, the drag coefficient of the wide single bevels is not a factor. If I were hunting out west and shooting 60 or 70 yards, maybe I'd make a different choice. But maybe not. I've yet to hear anyone complain about missing because of drag coefficient. And the Iron Will, from what I can tell is well-regarded in terms of accuracy and flight characteristics. How important is 0.1 in terms of DC? I can keep my field points and IW Wide 125's and 2.25 Tac Divers in a 3 inch circle at 40 yards and under, which is all the farther I shoot anyway.
At the end of the day a Flex Fletch FFP-187 and Iron Will Wide 100 can still be tuned and shot accurately for "typical" bowhunting distances.
This will be my first year trying a mechanical for deer and I opted for the Sevr 1.75. It looks like my vane selection is in the top 20% of the test in all regards so I don't see a reason to change
