Either way really would work. With the lofts we have today, the GW is basically the equivalent of what a PW use to be and most liked the PW to be a part of the set. So the GW is the extension of the set and you might like it better in the TS3 vs a stand alone GW. That being said, a lot of players will move to a Gap wedge in a wedge specific design, like our new DRT. I personally play the TS4 in through the PW, but put the DRT G grind 48 in as my gap, and then the 52 S grind or A grind and 56 S grind or A grind. Which 52 and 56 I use depends on the turf. Neutral to firm I use the S grind, neutral to soft I use the A grind.
So, on the GW, I would go with what you like to look at more that anything else.
