Like John said and he would know, the black mark indicates stiff in spine.  John helped me out over several phone calls when I got started.  Thanks John - I hope life is kind to you.

I shoot .400 spine shafts 29 3/8" long with a 250 gr. point in an aluminum insert out of my 58# long bow.  Each bow will be different due to where the shelf is cut and your release.  Try the .150s that you now have with more head weight until you tune.  That is my thoughts and do some bare shafts.
