I don't care for them. Going to use the 4" Savage duravane, 29" Beman ics hunter elites 340, 100 grn. Thunderheadsthis year. The savage is around 9 grns a piece. That's less than 10 grns. over the blazers which weight 19 total (3) on my scale. They are also a lower profile, (less contact issues).Then again if you shoot with a biscuit your stuck with them. The savage is supposed to work with the biscuit, although I can't say they do.
