I'm currently doing research on the new GT280 mini driver. I've looked at pictures on GolfWRX for how the pros are setting up their bags with a mini driver in play. I've seen pictures with different weights in the back and front for each one. The most common set up I see is Dr., Mini, 7W, next iron. I know the answer is go get fit but it seems to be a lot of pros playing the same driver shaft just heavier.
