Always enjoyed my Speeder driver shafts. Began using the Speeders years ago in a 983K Titleist. When I got my XR16 it had the Speeder. My fairways have Fubuki shafts in them. Ended up with a Fubuki driver shaft. It just didn't seem to have the same feel/response as the Speeder.
Tinkering, I chopped an inch off the Fubuki driver shaft. Made all the difference in the world. Just as long... or longer. Much more consistently in the fairway.
Full disclosure... I don't carry a 3-wood. My "fairway" wood is a 5-wood adjusted 2 degrees weak. Depending on the day, I usually have a Mini 1.5 in the bag. It's also set +2 degrees. The Mini has a Kuro Kage in it.
