I'm getting ready to start working on an english project. The assigment is to write a set of instructions. This is for "Technical English".

1. What's the term I'm looking for when I'm saying there are two type of bow 'shelfs'. The traditions that the arrow has to 'bend' around and the modern 'center-shot' shelfs in the risers of compounds and modern recurves?

2. Are there any areas of tuneing or bow-setup that you feel are commonly ignored? (this paper will deal with mechanical release aided bows with the 'center-shot' shelfs)
