RE: See your arrow flight?
I can't see the arrow but I watch for the impact on the target face. That way I'm keeping a good follow through.
I wish I could tell what the arrow is doing but it's tough at 300fps. I use white blazers and can see the white against the Yellow Jacket target for only a split second.
If I step out to 40yrds. I can see it's paththe last 10 yrds.
