OK, so I'm actually pretty deficient in this area.  I never grew up spining arrows.  I never spined my Manchu arrows formally-because of my draw weight and poundage, Forrester custom-made me a set of shafts that I couldn't bend when I shot 120#.  They were nearly 1/2" in diameter.  Hit like a freight train (they were leopardwood for weight and durability.)  However, I am going with rivercane for my next set of arrows if I can.  I have shot rivercane, or hill cane, or switch cane all my life.  I'm however not so great at picking them out.  If I cut 24, 6 might make the cut.  Those six were laser beams.  I got used to shooting anything and adjusting technique for it like Pop taught me.  However, I'm not able to talk to Pop anymore, as he's passed on.  I passed the warrior initiations, but I never learned everything.  So now I'm stuck.  I can make a good arrow.  That's not my issue.  But making a proper arrow (by our standards) is much much harder, and I don't know any elders to ask.  My band is almost completely gone-I may be the last of our offshoot still practicing and not gone completely "mainstream" (which is a poor word, but it kinda conveys my meaning.)  
I looked at Khan's arrows.  They're really good work.  But I don't know how I feel about tonkin.  I know it's awesome, if it's anything like the madake I've shot.  I know I could talk to him, get some with points that I can finish myself, and rest easy.  But something in me says that's too easy.  I'm confused and missing information.  I don't shoot like a European.  I can shoot Asian just fine, but I finally just wanna shoot Mvskoke and now i don't have enough information to finish everything.
Sorry for the rant, but it's giving me fits.  And bad sleep.
