Here you go shewe. They are taller, their forward angle is more abrubt, they are thicker, stiffer and textured. All this increases their drag in the air. Plus they are more quiet and a ton more durable. Plus they are a bit lighter. I've shot them through the corner of a foam and bag target and they didn't distort. The only problem I've encountered is vane clearance in my compounds. They install nicely in a helical and they can be set with a lot of helical although I've seen no advantage to an extreme helical in the accuracy department. Oh I forgot, you will acutally save money, I found I have to refletch much less. They don't seem to be easily damaged when shooting groups.
