I don't know that aligning fletching helped mine or not, but I used a piece of sandpaper to take a small amount of material off my inserts, that allowed me to customize each broadhead twist to line up with fletching. It worked great and my Montecs shoot as well as field points. The material removed was so small it didn't affect weight, flight, or FOC at all.
Just a tip... it was easier than re-fletching.
