i assume you use alc 120?!
i personally would always try the standard Safedisc-profile (NOT the 2/3-profile) first.
because IF this works with the safedisc-profile, it's nearly a "perfect" copy, without any kind of methods trying to "fool" the copyprotection.
if it does not work, use the 2/3 profile, which uses efm-correction, which i, personally, find is a kind of weak emulation. and i just don't like any kind of emulation...
