I am thinking of getting some Gold Tip X Cuter shafts. I currently shoot 29", 63lbs, 65% letoff, release. I am shooting a Hoyt Havoc Tec with the excel Cam.
How do I know what weight nib to shoot with the new shaft?? Is there a specific F.O.C. i should be looking for?
What is a good size Vane to shoot with theese larger shafts? Mostly indoor and 3-d shooting.
Thanks for the help

I shot those shafts for half a season. They are a heavy shaft. If you like to run on the edge of being IBO legal you my have a problem. They are 9.2 per inch also they need an uni-bushing for the nock. They are durable.

Those shafts are very stiff as well as on the heavy side. Try to load up the front end with weight to lighten the spine. 3" vanes are the most popular for that type arrow that I have seen. You might think about the CXLs or Vapor speed 23--they aren' t quite as big as the xcutters but are offered in more spines and weights. They are the size of an aluminum 23 diameter shaft like a 2312.

you can go on the intrernet and search for asrrow calculator. Look at the hits there and you will find a site that you can choose the type of shaft you are shooting and all the extras and it will calculate arrow weight and foc for you. A good Foc from what I have read is 8-13%.

I shoot the XCutters from my ICON. The Icon is 70 lbs at 28 inch draw. I shoot a 26.5 inch arrow with 70 gr nibbs and gold tip' s unibushing with Easton nocks. The entire arrow weighs in the 334 gr range. I checked out this arrow to my set up on Archers Advantage program and it basically laughed. It said this arrow was way too stiff for my bow. It recommended a 29" XCutter with about 125 gr nibb before it got into the green (good spine for my set up).

All I can say is they shoot great for me. A good friend of mine shoots about the same length arrow as I do with a 50 gr nibb and this guy gets good flight out of his arrows.

A lot of people want to go to about a 100 gr nibb for the large diameter carbon shafts, but I think it is trial and error. The only thing I would caution you on in the experimental stage is this... If you epoxy these tips in you may damage the arrows getting them out. You might want to carefully hot melt the tip in and see how it flies. If it is not up to your standards then add some weight and go again. Once you find the right set up then epoxy the points in.

I am currently shooting the x-cutters with a 80 grain nibb and 27 1/2 inch arrow. I tried shooting the 50 grain nibbs but I couldn' t get them to fly right on 66plds but with the 80 grain they seem to do fine. Now you could try the cxls, but be prepared to buy a couple of dozen because their not a very durable arrow, but they fly really well.
