You don't run the spool with a center one-way. You definitely want the locked center shaft to go with either a spool or a front diff.
At our local Hobbytown parking lot races, I use a locked center and a front one way. We cannot use spools cause the turns are way too tight to work. None of the expert drivers here have made them work. I'm switching to a front diff (as soon as parts arrive) cause that's what all the experts use no matter what the brand of chassis.
Try it with the one-way and see what you think. Remember you cannot use brakes. It's great for hot-laps, but gets really difficult to be aggressive in traffic. Brakes and alternate lines seem very necessary...
Spool & locked center are good for real asphalt tracks...
