i think i heard somewhere that on here you can equip the different lofts of the driver in different spots at the expense of other optional clubs. I don't know the exact degrees of each loft of that driver, but here is an example. Lets say normally you play with a driver 3wd and 3 wedges outside your iron set and putter. If you want two different lofts you would equip lets say the 9.0 and in place of the 3wd the 10.5 and then your 3 wedges. At the expense of one of your other wedges you could equip the 3rd loft and have 2 wedges. Basically like carrying 3 different drivers.
I don't know if this is accurate exactly, but when i first read about it I was under the impression that this was possible
