and I have been told that the centre of the arrow should be aligned with the centre of the threaded hole.. Not sure which is correct..
I tend to follow this thread and have been doing so for many years.
When setting the knock position, what is the reason why the knock should be 1/4" higher than the pefect horizontalposition? Is this to accommodate the knock? Or is there another reason..
This is a good starting point for setting nock height. Actual nock height is going to vary depending on your individual setup. Such issues as cam style, rest tension/style, arrow spine, etc... are all going to play a part.
