Those shafts are very stiff as well as on the heavy side. Try to load up the front end with weight to lighten the spine. 3" vanes are the most popular for that type arrow that I have seen. You might think about the CXLs or Vapor speed 23--they aren' t quite as big as the xcutters but are offered in more spines and weights. They are the size of an aluminum 23 diameter shaft like a 2312.
