2x 6950's shader unlocked in crossfire

Running http://bitcointalk.org/index.php?topic=3878.0 poclbm-gui under local solo mode.

Currently have "Default" setup generating on device 0 cayman. Should I create another one generating on device 1?

My current Mhash/s is 272/s. Is that good? How many khash is that?

Are there any extra param I should be running to make it more effecient? I remember seeing something like -vectors.

Am I generating enough that it's worth it to stay solo or should I join a pool?

Thanks!
