How to copy lines with identical attribute values based on length?

I'm using ArcGIS 10.1, Advanced license.  I'm working with file geodatabase feature classes.  


I have a line feature class called sticksRF_2split.  Each record in this feature class has a unique value in a field called PROPNUM_GIS.  I run this feature class through the arcpy.SplitLineAtPoint_management tool.  The output, sticksRF_split, has two records with the same PROPNUM_GIS value.  From these pairs of matching PROPNUM_GIS values, I want to create a feature class that contains only the lines with the greater value in the SHAPE_Length field.  


I'm thinking the necessary approach would involve a dictionary with PROPNUM_GIS as the key and SHAPE_Length as the values, and then compare the values.  I'm having a challenge finding any documentation about how to accomplish this.  Is this the best way to approach this problem?  Any advice or suggestions would be greatly appreciated.
