I have shot the Heritage 90s, and they do well. However, I do not like the feel of a skinny serving, and when I built my serving up to where I had to sand the sides of the nock slightly, they would break, on a diagonal on a regular basis. Break would start at the bottom of the string area and run down close to where it meets the shaft. Bought additional nocks and swapped them out on a regular basis, but still had an occasional break. 35/55s from gold tip or beman should serve your purpose.
