4 wing footings look beautiful, but hardly really add considerable impact strength to the arrow. It takes a long time, is messy and cumbersome. Especially the reduction of the 4-wings into the arrow diameter.
The conical splice, which the arrow-fix or the rep-arrows are using are much better for impact strength. I was shooting 1/2 doz. 4 wing footed cedar shafts footed with Jatoba (in the ironwood family)into a concrete landscape block. All 6 splintered and shattered along the arrow shaft and made the shaft completely unusable/unrepairable. After that test, I shot a single cedar arrow, footed with 1.5" of black locust wood behind the point using the arrow-fix conical splice method. I was shooting the arrow 7 times. After the 7th impact, the field tip split along the ferrule. The arrow is still fine. Distance for all shots was about 11 yards and with a 60# longbow. Assuming, that the little footed arrow would have broken off, the break would have been right behind the point and could have been easily repaired again. I have 1 arrow out of my 3D-shoot set, which is repaired 5 times within the first 4" behind the point. Works fine. I am currently evaluating hickory and ash....which can be bought in arrow shaft diameters...
