So we all know that positive angle of attack with a driver will yield more yards
Hitting up by itself WILL NOT yield more yards! What you want to achieve is the optimum launch angle for the ball speed and if possible the optimal spin. Optimal here is maximum distance (either carry or roll)
So what will hitting up really do for that ball data : it can make the loftspin lower therefore generating less spin. However as seen by hitting down most people keep the spin loft the same
It will increase launch angle. As the launch angle might now be less optimal you might need to take a driver with less loft to get again back to the optimal launch angle.
Less loft is less spinloft is less spin. Less loft might also improve on the maximal smash value so increasing possible speed and thus carry
To know what your optimum is you need to know your ball speed. And then calculate your optimum or let a clubfitter do that for you. Then find the max AOA you can achieve without to much trouble and from there find the correct launch, then the correct loft that generates that correct launch....
If you need max distance also with your 3-wood : start using the driver instead!
if you have the best distance with the 3-wood then you have not enough clubhead speed for the driver your are using!! Find a clubfitter unless you're on of those "I don't like anything higher then 10* loft" macho types.
