Two comments:

First, I wish there was a way to time out modes without waiting. I think that having there be a reasonable decision point on the game between playing or not playing modes is an interesting rule: I just wish it didn't take 30 seconds. Use the punch it! or start buttons, maybe, to immediately set the mode to 'final shot'?

Second:

Sk8ball commented in an earlier thread that the doubler for DtD was actually the warp ramp. He was hoping he could cash in some sweet vengeance at double scoring and was sad.

Not true. The little red light on the warp ramp "insert" floating above the ramp lights for combo, I believe.

Is Katana Mode Multiball in lieu of the last one- or two-captain's chair modes? That seems... poorly thought out.
