Best flywheel so far?

Many people have posted opinions and such but what is the best flywheel in terms of stability and accuracy. What are the pros and cons of a single wheel and a 2 sided one. For a two sided flywheel should the shafts be vertical or horizontal. Also what angle and gear ratio do you find the best?

We use a single flywheel which works really well for us. We experimented a bit with a double flywheel(horizontal) but we decided that a single flywheel was better for us. I think you should test and see what works best for you.

What gearing and how many motors do you use for your single flywheel?

It has 4 speed motors with approximately an 18:1(5:1, 5:1 5:7)

It gets the high goal at about 75 power.
