I currently shoot Port Orford Cedar 11/32 shafts, cut to 30 inches. I shoot a #55 takedown PSE "Raven Series" by Jeffery (Jeffery was comissioned by PSE to build the bows). I pull it to 29 inches, which makes it about #58 lbs. The shafts are spined to #55-60, which I bought from Suzanne St. Charles at Northwest archery (google it and it should come up, she is an arrow maker...)
Since you are shooting a #65 bow, you might want to think to the other end of the spectrum, and go with weight (wood) vs. speed (carbon/alum). I would shoot as heavy an arrow that I could get to fly straight out of that thing, maybe even try Boca or Hickory shafts or some other hardwood.
As for broadheads, I shoot Zwickey eskimos (2 blade, no bleeders).
If you study the Kinetic energy of an arrow, you will see heavy and slow beats fast and light anyday...one more reason why I am thinking of either upgrading to a custom bow by a boyer in the #65-70 range, or getting some new limbs for my recurve in that range. I am slowly turning from a deer hunter to an elk hunter, and want pass through penetration.
If you haven't already subscribed, spend the $20 and order Traditional Bowhunter magazine (it's published in Eagle, Idaho). They just had an awesome 2 part article about arrow penetration that discussed shafts, and broadheads, including some minor things that can be "tuned" within the combination itself...
good luck, and shoot often.
