Neither one of them really improves much on the 215 Hybrid. I was excited for them, then I saw the bearing surface length. The 208 has nearly the same BC as the 215, but it has a slightly longer bearing surface. So really it won't be much faster or offer much more ballistically. The 220s look better than the 230s, but don't think they'll be an improvement over the 215s. Again, they have a G1 BC of 0.717 vs 0.691 of the 215, but have a longer bearing surface and are 5gr heavier. I don't see them offering much out to 1200 yards.
