Since we're close to the topic, I'd appreciate seeing opinions on head angle vis-a-vis the various high-tech levers. There has been only a little discussion on it in the past, at least that I've seen.  I'm currently using a Schaff lever with a 5-deg head (after stripping the female pipe thread on my 15-deg head...)  I like it better except for having less clearance over plate struts and the occasional big ol' upright.<br> Tks<br>Paul Bruesch<br>Stillwater, MN<br><br><div class="gmail_quote">On Wed, Apr 9, 2008 at 3:17 PM, Joe And Penny Goss <<a href="mailto:imatunr@srvinet.com">imatunr@srvinet.com</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div bgcolor="#ffffff"> <div><font face="Arial" size="2">The shaft end is.
