I just bought some new Easton Light Speed arrows with blazer vanes on them. I am using a 100 grain head and the setup weighs 361 grains. My bow is a Mathews MQ 32 set at about 64 lbs, and the arrow I was shooting before weighed 389 grains and I was shooting about 260 ft per second. I am not sure how fast I am shooting now, but I am sure it is a touch faster. My question is are the light speeds a good arrow for 3-D combination hunting? Thanks
