cutting string angle on nocks question

[dragonman]

what is the optimum string angle that should be cut into the nock for a 70" longbow? I usualy cut them at 45 degrees , this seems to work for my 26" to 27"  shorticsh draw,  but recently made a bow for someone with a 29" draw and the string pops out of the groove at full draw. Was wondering what angles others cut into their nocks?

 The nock should be cut at the angle that matches brace height and widened at an open angle that will accommodate full draw. It should not be a simple slot that only looks pretty at brace.
