I had a dozen Sitkas. I gave them away. I lost more inserts and had the tips split just shooting into an excelsior bale. Yes I was using what ABS recommended glue for the inserts. I was using them for tomato sticks, since I couldn't recommend them if I were to sell them. Someone wanted to try them so I gave them to him.
CX Heritage shafts for me - heavy, tough, shoot great (bare shaft to 40 yards) and much cheaper. Although I am going try douglas fir in the future.
Save yourself some money.
