Tim on the subject you bring up, if you get in a SAFE position near the arrow's flight path, I believe most people will notice that wood arrows are quieter than carbon and especially so than aluminum. The advantage in quietness of parabolics over shields is evident as well.

I have shot at five deer this season and none have reacted to any substantial degree. Four out of five are in my freezer. The one that isn't I only wish he had reacted. He was an 8 point in the low to mid 130" range. I just flubbed the shot.

All that being said I have had seasons where they all reacted and I am using the same setup. Why it has been that way is anyone's guess.

Perhaps our deer aren't as wired but I have only aimed below the deer on the ones that I knew would react. I do aim for the heart and many times that's where the arrow goes.

In no way am I an expert but it has worked for me for years.

Low and Tight!

Sometimes deer jump the string and sometimes they don't.  It's a pretty safe bet they will when they're alarmed/alert. On the other hand, I know from experience, mine and a lot of fellas I've hunted with, that we don't always shoot where we think we did.  There's a real tendency to shoot high from a tree, and most times we we attribute a bad hit or miss to the deer jumping the string when it's our own shooting that's the culprit.
