It seems they don't have the option for the titanium ones anymore, just steel and modified steel.
"CompCams 7˚ titanium retainers are American made from 6AL4V alloy and then heat treated. For performance without compromise these retainers deliver! Titanium retainers weigh 7.5 grams."
EDIT: Intense has some titanium ones also.. $149.00
