See if I understand your question. The tradepoints I make weigh the same as what I had been using broadhead and target point, so arrow length wasnt an issue for me. The broadhead taper is slotted to except the tradepoint just as a glue on would have slid over the taper. I make my own shafts from boards so I know what my spine needs to be and can sand all shafts to exactly what I need. Once I place the tradepoint in the slot with jb weld, I spin test using a gauge with a straight line at the point. As I spin I watch to see if the tip of the head moves left or right of the center line, and adjust the head until the tip stays pointing at the center line. Then clamp and let dry over night. My home made shafts and tradepoints fly great. A huntig partner of mine razzes me saying my broadhead arrows fly way better than my target arrows, and thats OK with me.
