I figured 1-up had to be with a spin to be anywhere close to as fast as 2-up in most conditions.
Yep.
Are you saying in 1up could you use a jib?
No - 1up = main + spi only
That said, having the option of putting the jib on when singlehandling can help liven up otherwise dull conditions. Of course, you can't race as F16 like that.
