I'll accept that they're minimal and not important, but not that gyroscopics have absolutely no effect.

It appears that geometry is similar to dihedral in giving inherent stability, and is far more important than gyro effects. I'll stand corrected.

I don't think that two opposite spinning gyros would cancel out, I think it'd be twice as hard to perturb the axis, but I could be wrong. If anyone knows I'd like to learn, if it's a long explanation go ahead and email me.
