PA-
Norbs statement isn't totally true however. There are plenty of low brace height bows that are less efficient then higher ones. The reason they produce more speed and power is called 'string time'

The arrow is simply on the string longer and getting pushed longer than a higher brace height bow.
Here's a perfect example:
PSE Tazman...1999 model brace 6.5", IBO 305, BPF 1.18.
Mathews SQ2....Brace 8" IBO 305,BPF 1.24
Again this only one example where a less efficient bow only produces speed from string time. There are a whole gammut of things to consider when trying to find your perfect bow. This is one of the reasons I wrote "The Archery Program" It was really fun doing all of the research, and seeing it work daily in doing these exact trials before you even pick a bow up!
Oh well....we could debate this for years!
It was fun, nice chatting with yah,
Happy Shooting!
