Oh-oh,
I may have a problem. Since reading this I did a bit of measuring and am coming up short on my arrow weight. Can comeone tell me if I am shooting the wrong arrows?

PSE Carrera
70# draw weight
30in draw length
29in arrow
100 grain broadhead
3 blazer vanes

I come up with 349 grains - am I wrong?
According to Carbon Express the CX300 I am using is ok. They list it at 8.1 grains/inch. Blazer vanes are approximately 5grains/vane(?).
