Chronographed all three bows with the four arrows, with a three arrow average and was a bit surprised. The 2219 (675 gr) went through the Big River(66.2#) at 172 fps, MOAB (63#) at 173 fps, Kestrel (60.2#) at 167 fps. Not a big spread in speed with a 6# range in bow weight. The 2315 (635 gr) went through the BR at 179 fps, MOAB at 177 fps, Kestrel at 176 fps. The footed Cedar (713 gr) went through the BR at 180 fps, MOAB at 164 fps, Kestrel at 162 fps. The Parrallel Cedar (630 gr) went through the BR at 173 fps, MOAB at 171 fps, Kestrel at 163 fps. This test/comparison was accomplished in @50 minutes, so could be somewhat skewed. The Footed arrow from the BR for example. Consistently of draw, anchor and release could also be questioned. The Kestral was shot about a dozen times after the trial at 20 yards and was within @8-9" group even with my hurried shooting. Accuracy wise the 2219 was the most favored of the arrows tested. 2315 had the fastest average speed. Tapered Cedar, tapered Red Balau, tapered Ash and Hickory were not tested due to time constraints. But I will tell you that one 2315 is missing most of one feather. All groups through the chrono had feathers touching, so my focus was good.
