I've seen folks group target arrows decent with funky tune/form.
Come time for broadheads and they freak out.
Some folks have been at this for a while and still don't know what a good tune/flight is.
Until they see it (actually don't see it)
Went round and round w MBA guy at work.
Range trip had his jaw on the ground.
He did some stuff and saw improvement, got to grouping finally, and thought he had arrived.
Nope. He merely saw a positive trend. And stopped short of the goal.
I tuned his rig and let him shoot mine. Was an "AHA!" moment for him (and last MBA I'll ever help LOL)
Had a bowyer and his buds at indoor range. Loud bows. Not fast either.
I shot my perfectly tuned Widow and they were amazed at the speed/quiet in comparison.
Guy asked to shoot it, and I let him.
First thing was "hey I can't see the arrow fly".
His lightbulb came on.
FWIW I think Widows easy to tune.
Maybe not the fastest, not the most quiet............but certainly good enough for me.
Like the mass weight.
And the way they feel on the draw.
