Not even counting the time spent shooting bows as a youngster, I've been shooting for about 50 years, off and on, mostly on lately.
Shot wooden bows, fiberglass, fiberglass laminated, shelf, no shelf and all kinds of arrows that I know now were mostly too stiff. First shot of a new set of fiberglass arrows 40 years ago, I hit the wand I was shooting at. Arrow didn't know it was too stiff. Been making my shafts for a half dozen years now. Usually check spine, but sometimes end up shooting odds and ends of different batches made for myself and others.
In all that time, NEVER ONCE had an arrow "kick" on a GOOD RELEASE. Bad release, all bets are off.
I know I'll never be as good at this as some of you who can make your arrows kick, porpoise, fishtail, hit point high, point low, fly left, fly right and who knows what else.
My hat is off to you.
