This is a great discussion, I've been trying to come up with a good 'rule of thumb' for how to handle this myself and had been under the impression that you want to keep the sheet on and play the traveler in the puffs to prevent the main from getting too much shape, power, and drag. Playing the traveler can be tricky, I've found that it doesn't always want to move when the sheet is fully on, looking forward to playing the sheet this coming weekend instead. Thanks guys!
