Spine weights average 31# =/- 5#
They average 30" long.  they came from a dried linden log that I got for wood carving.  They are oriented with the straight grain running  their length.  
Butts are tapered from the foot joint to the tail just slightly.  I use a grinding jig to rough in the square blanks then hand planes and sand paper to round them over.
Forgot I was out of tips.
