Ok, now we're gonna see who's oldest and hasn't yet lost his memory! I don't think Swifts were the bottom of the line....they WERE the line. And, yes, they bent like string cheese. Then, Easton came out with 24SRT-X, which was the early XX-75 material, but still in the aluminum color. It was harder and resisted bends and priced so it appealed mostly to target and field archers. At some point, I'm guessing about the time the Autumn Orange XX75s were introduced the Game Getter became a second line, camo-colored, softer-but-cheaper hunting version. XX-75s and GGs have become camoed differently now, but I believe the materials are the same.
I still have several hundred Swift shafts, mostly in the 1920, 2020, and 1818 sizes which are dinosaurs, in themselves. If you have some Swifts and enough inserts for them, don't give up on them. They are great practice arrows, and even ok for stumping....they're a lot easier to straighten than the newer, harder alloys! And, my opinion is that Easton's move to larger diameter, thinner walled shafts was a marketing decision....more spine versatility, and more line cutting for 3-D archers. I think a smaller- diameter, thicker-walled shaft is a better hunting shaft. (no disrespect intended to anyone, but what is the intended market for a 2512 shaft?)
