Copy that on premature center serving wear. Not a fan of downward pressure bowstrings.Many bows ( my Mission Dagger as an example) have trigger claws that drop downward, the string coming out over the top of the dropping claws. I believe the down pressure helps keep the string from jumping over the nock. The Mission has, what I consider, a ridiculous amount of down pressure, but due to the fixed design of the cams/spacers, there is nothing that can be done about it. That string does hit the nock in the center, but the down pressure causes the center serving to flat spot pretty quickly. I know Barnett and perhaps some others have the arrow/nock sit high on the rail, and the string hits a moon nock below center. Not sure why they do that ( other than trying to prevent partial dry fires), but they’ve been that way for years.
