crucial, cause if i dont say, (cf) will steal my RBX and ehiem 1250 . but nah, crucial because of its versititlity, being able to do 230 1.5-2-2 and 260 2.5-2-2 at 2.8-3.1v.
Voted crucial to better justify my purchase of 2 of the 1gig Ballistix sticks. Also, they do things for the A64 that the TCCD/TCC5 just isn't able to do, such as high speeds with decent timings.
