Most pros would agree that there is no benefit in aligning BHs with fletchings. I'd love to see some rationale or proof from those that do. Also, there is no way someone is going to do an exact tune for you. They can get you close, but ultimately YOU will have to fine tune your bow so that BH's hit with field points. Having arrows that spin true with no wobble is key, not fletching/BH alignment. If it gives you confidence, then have at it.
