Has anyone tried Brass cartridge mounting screws?

Mounting screws should be aluminum or titanium for best sound.

I use aluminum screws with blue tack between the cartridge & headshell. It works well. 

I bought the Soundsmith EZ mount screws because I wanted that easy method of securing my cart, I really hate the bolt and nut system, you need 6 hands to attach and then when setting up is a PITA. The Lyra helps since its threaded, love it for setup!!

I did find that the brass, alum and steel had a different sound character....but this was because of the position of the counter weight. I found the stainless got my counter weight as close to the pivot point as possible, the brass ones pushed the c/weight way back.
