Shaft Choices for Custom Crossbow Arrows

[nksmfamjp]

I have a couple of questions. . .

First, what diameters of shafts work best on your crossbow by brand/model?

Second, what arrow shafts have crossbow nocks available for them?

For example, I shoot a Tenpoint Magnum X-2. It seems like a 22/64ths or 21/64ths arrow are all that fit the rail properly. I'm using 2216 and 2219 arrows.

For aluminum, I think only Easton 2216 and 2219's are available with crossbow nocks. Although, I'm planning to start putting inserts in both ends to add weight and to allow my homemade arrow removal tool to work. It is a field point epoxied into a pull start handle.
