The 350 gr minimum includes point. A lot of the Excal shooters prefer a slightly heavier arrow, as advised by Dan Miller [740] 483-2312, talk to him, nicest guy in the world. I use Boo strings [FFF] w/ 431 gr arrows out of both Phoenix and Emax. His strings have far more serving life than factory ones, at least double, imho. He hangs out on Huntingnet or Excal forums. W/ a 22 series shaft, your string hits the middle of nock. W/ larger diameter shaft it won't, which may cause you some problems, but Miller will know for sure. You can use half moon nocks in your Excal, popular opinion is the flat are more accurate. Btw: these 431 gr arrows are nearly identical to the ones 10 pt uses, which should tell you something, lol.
