Jeff: When we spoke last night, and I referenced guys shooting 90 meters with a 5" sight extension and being VERY accurate, this is why they are shooting 5" sight extensions. To move it out further, they have to drop the scope lower than the arrow will allow them and they end up with fletching/scope contact. So they compromise with a shorter sight bar, and raise the peep a bit so that it maybe isn't 100% solid, but still repeatable.
