Thanks Dan that does look like the sort of thing I was after. Just tried to install though and it will not let me as I have limited rights to my work computer but if I get a chance I will try get IS to install for me.
On another note the map I was doing on Friday got changed on Monday and the request was now for one of the labels to have a three colour circle. After a quick search I found this page http://mappingcenter.esri.com/index.cfm?fa=ask.answers&q=1395 and installed the Esri wedges fonts from Mapping Center's ArcGIS Resources - Styles page. Great font to have with different size wedges to use
