The First set of ratios is really nice for around a 4" Wheel. It allows you to get a really nice choice of reductions. We do a 14:45 with a 15:60 - 30:45 shifter set to get around 16/6 FPS. Which is really darn nice. Wanna gear faster or slower? Change the input ratio.
But the ratio above allows a really nice, compact gearbox. If you went to a smaller wheel ~3" Or so you could go to the smaller set and use the Latter ratio.
All the information above is for a 2 stage 2 speed, you can use either one if you go to the three stage. Its just more weight/money/less efficient.
If you have any questions, please post them up!

Wow, That's something that I did not know. I will start working with my design team on designing the gearbox.
We have been confused about this for about 4 weeks or so, and it just hit me that I had a huge and knowledgeable community right here on CD. I'll be sure to keep everybody posted if I have questions.
