Switched to 5 ball last night with some friends over. After they left I put up almost 700,000 on the first game (had gotten within a few thousand of 400,000 on 3 ball. Got to melting the witch (but didn't - didn't even realize what was happening till it was too late). Might keep it on 5 a while but hard to say. 3 balls just feels more challenging and like you really earn your progress.
