Shoot what you want.
Use em to aim ,don' t. Up to the shooter.
I would suggest that comments about a shooters equipment such as the ones referred to here,( about nocks) reflect upon a persons sportsmanship.
I would also suggest that constructing ones arrows specifically to preclude a competitors ability to see an arrow in the target also reflects an attitude about sportsmanship.
Both wrong.
To sum it up. Build em the way you want them to look. Marvel at how nice they look, and enjoy the shoot.
