was wondering if anyone had any experince with these heads i just got six of them like the idea of having a changeable wieght ferrul

I used them for several years and they are a quality head that flies and penetrates very well.  The interchangeable ferrules make a good head even better.  They need to be sharpened but the hard steel takes and holds a good edge.

I've used from here to Africa-great heads!!!

I was just about to type what SlowBowinMO did so i will just say Ditto

whats the best way to sharpen them? or should i save the time and everyones breath and just get a kme

I have some in the box...kind of a BH junkie as I like to buy em faster than I can try em out.  Glad to hear all the positives though, need to go put one through a javelina SOON!

bowmaster12, sharpen them like a Woodsman or Snuffer.  There are several tutorials for those on this site which should help immensely.  The KME isn't intended for 3 blades, but is fantastic for 2 blade heads.

I have used them for several years with great results.  In fact, bought some other brands this year and never could get myself to take the razorcaps off my arrows!

Be sure to sharpen them, if you don't they won't work well.
