ftr - 80 min discs won't work in my MS722's, so I only use 74.
I"ve used:
Maxell both normal and color
Memorex both normal and color
hispace
sony gold, color, and normal
jvc color
phillips color
tdk gold ice normal
etc
shit, a lot of others, quite frankly i think i've tried everything out there and i'm fully partial to the sony colors. they're the only disc aside from the TDK ice that have never defaulted on me once and as well they are cheaper than the ice.
