^^ So you're the one causing a shortage of Aspide Arrowheads...
OP - those ass-o-meters are not very reliable. I got measured for a 145mm Bonty RXL, and also got a 143mm Toupe after that. After a bunch of riding, I find that I am happiest on 130mm saddles - Selle San Marco Aspide Arrowheads that the runningDoc hoards, as well as the 130mm Toupe.
So dont trust the ass-o-meter and limit yourself.
