Boeotian/Dipylon Shield

[Chris B]

I have two questions and would greatly appreciate input. I have read the many posts on the Boeotian shield and just have two issues. I have seen several vases with an offset porpax and grip closer to the edge in a vertical position on the shield, but I have also seen some that simply have two strips of leather or perhaps rope in place of the porpax. I have also read here about a possible center grip. What is the most accepted method of the three if there is one? The second question I have is of which shield patterns may have been more likely on this type of shield. I recently posted photos of an aspis I made with a pegasus as the pattern and would like to have something quite different for variety. After building the aspis, I have gained enough confidence to make a Boeotian and would like to start work fairly soon. Any thoughts are appreciated.
