RE: shaft selection
Get beman matrixs and get the best of both worlds , or acc's if you can afford them , You will save around 100 grains over the 2314's or 2315's you would shoot . Lots of guys are useing the beman ics shafts allso with great results . These shafts have smaller diamaters than the alluminum and penitrate better , but with your spec's you should not have a problem with that even with alluminum , If you are on a budget I'd stay with alluminum as cheep carbons are just that cheap and inconsistant .
