I will recommend a 3 or 4 blade cut to tip head.
Look at Razor Caps, Magnus Stingers, and Muzzy Phantoms, off the top of my head. There's a bunch of good ones out there.
I'm using Razorcaps out of my 52lb longbow.
I chose the RC's because they are nearly identical in profile to my favorite 3 blade'r, the Woodsman. Yet the RC's are stainless (no rust), no glueing, offered in 125 grain and are very easily resharpened.
I nearly always have complete penetration and plenty of blood with the Woodsman and low # bows. Can't see the RC's being any different.
