#6 Drives VS. Ratio's ?
 

Everybody seems to have there own opinions and they all seem to be different. Hoping I may get some great answers here.

Currently I have two ratio's 1.5 and 1.61 I was going to run the 1.61 but was told I may run out of easy to find prop selections and so I should change everything to 1.5's

I only want to set this up once.
So the question is If I have the power to push any gear and or prop.

What's the best ratio to push out of all the gear ratio's offered for the #6 drive?

Thanks
