Footing: Goldtip and Easton Excel

Need some help. Anyone know what size aluminum shaft it takes to foot Goldtip's (Entrada's), and Easton Excel's?

Is there a chart somewhere online? May be a good project if not.

Thanks

Try this.  You will have to measure the diameter of the shafts.  I had tried footing GT Expedition Hunters in .400 spine and 2113 fit them nicely.
Not sure if carbon arrows vary the inside or outside diameters to hit the specific spines indicated on the arrows.
