Proly 30 recurves over the years.
None shot cock feather in.
Never needed to.
If such helps your arrow/noise flight............you've got something going on that needs fixed.
Sounds more like a bandaid than a fix to me.
But do whatever.
Confidence is an important thing. Whatever works and builds your trust.
But make sure it really is trustworthy.
Can't argue cause I'm short on experience here. But the arrows are flying sweet, little to no bow noise, and I'm getting as good a group cock feather in as when it was out. Only difference I can see is that the hen feather not getting all beat to heck. Granted, I could clock the nock and roll that hen feather into the gap, but it seems there is no need.
And as you note: "Whatever works and builds your trust". Wise words.
Thank you all for the sage insights.
