driving double ups

How big of a circle should you make when driving a double up? We have a nautique 2001 and the wakes are either too close or too small.

It's got to be wide enough for the rider to have time to cut out, spot the roller he wants to hit and cut in. I usually like mine pretty wide. If your wakes are too small you may just need to put more weight in your boat to make the wake bigger. I've got the same boat that you do, plus 2000lbs of fat sacs, and my d-ups are fine.
