hi kevin i am glad you have brought this up as i wanted your expertise on this  i guess i am still not clear as to when to use one versus the other and would like to get an explanation from you on the subject  looking at the code  i thought that  unless you have slaves to attach to  one should always use a slavetemplate  a  leaner  object i thought that one should use a mastertemplate if and only if you need to attach slavetemplates to  please clarify  thanks
