The Bob Kooi papers address this. Sharper angles store more energy but lower angles are more efficient. Clear? ![Wink ;)](http://www.primitivearcher.com/smf/Smileys/default/wink.gif)
Is that because sharper requires more thickness due to stability, or just because? Guess I should check out those papers again... yeah, they're pretty hard to digest.
Guess it kind of depends on what gpp you intend to shoot, too.
From what I understood reading, Adam Karpowicz says sharp is better (like in Turkish bows) because, basically, a straight line is shorter than a curve..

(Doesn't seem like it'd be a big difference though...)
I like in-between, more pleasing to the eyes. My beauty ideal is something like a Korean or Crimean Tatar bow...
