What does brace height mean? All I can figure out is that the longer the better. Don't know exactly what it means.

How about 1 cam vs 2 cam? I think 1 cam is easier to keep in tune than 2 cam, but not sure.

What about string stretch? Is that really a problem?

All this new technical stuff is bewildering to me.

I am thinking about a new bow, my current is the wonderful Cougar II, but I sure like the higher letoff of more modern gear. I was looking at the single cam on the website.
