Craig...although no expert this is what I have found.

Urethane is certainly better because the glass screen can take its own shape rather than being forced into a shape by the insertion rubbers into a frame. With the rubber seal the glass is forced to the shape of the frame. Any variation puts stress on the glass.

Would you believe my old RMC windscreen had 3 screens in it and I didn't even leave the car park at O'Brians glass. They all cracked whilst they carried the screen to my car.

This issue about notching the cowl to get the screens to fit is $rap in my book. Blu$$y hell, the frame section is brass...easily formed to shape. The problem is of course that all cobras are different in the cowl shape...even between bodies from the same mould.

I'm gonna make a template and get trevman to modify mine if he is willing.

Cheers
