If so, I hope he tightened mine the same way haha !!!
I have 3 glasses tightened by Zach and 4 tightened by XMan...
The XMan glasses leave dents in the side of my head hahaha !!!
The Zach tightened glasses feel awesome as they allow for some flex...
Unless Zach has now found the secret coupler and can make them super tight ??
Any really tight flex couplers are pretty easy. Seen some frames that people have used some sort of stiff polyurethane clear tubing just cut into short pieces and fitted inside the nose. Pretty much makes it so the nose has no flex. But kinda defeats the purpose of having a frame that was designed to flex to accomodate the shape of your head.
