The principle is keep the string segment reasonably short and the string deflection angle high enough to efficiently terminate the speaking length without it being so abrupt as to encourage the strings to break. I wrote an article on this once.</FONT></DIV> <DIV> </DIV> <DIV><FONT face="Lucida Sans">Del</FONT></DIV> <DIV style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"></FONT> </DIV></FONT></BLOCKQUOTE></BODY></HTML>
