My older Brompton has a 20 spoke wheel, hub is steel, so no possible Pull thru.
I'd say the issue is the hub choice, if there is a lot of metal outside of the hole ,
then fatigue of the aluminum, results in that being a lower possible outcome..
one benefit of a bladed spoke is it can be held to not wind up with the nip rotation.
Bontrager supplies a tool to hold the blade.
