I have a number of bows in that weight... they handle up to 1816's with 125 heads, but I get much better performance with 27" 1616's with 65 grains on the tips. I used 55 gr. points and put little 10 gr. brass screws in the backs of them. I've been really surprised at how these light arrows fly and at how they've lasted. I made up 18 in early spring and still have 14... only bent 2 and I was able to straighten one of those, which I'm still shooting (no hope for the one that hit a rock at Moses Lake!)... rest were simply no finds.
