[QUOTE="jon.henry755, post: 491130, member: 29115"] Hi Bob, You are totally correct on your spine assumption for the .250 shaft. I was hoping the .300 might work, but the shaft diameter also plays a big roll in the stiffness factor. That's what I was stating in my last response to Konrad when we were talking about the 11/32 (.375) shaft sizing being used for most crossbows. Most manufactures seem to be using the wider shafts to achieve the stiffness needed to handle the extreme torque produced by today's crossbows. When you do the math on these things it adds up to some very extreme numbers, so if I'm reading the numbers correctly, it also puts some limitations on what we can or can't play with from an alternative shaft perspective. I'll wait to hear what Konrad has to offer based on his research, but I'm fairly certain he's going to tell us that our best bet is still to sort these arrows by matching the spines and re-fletching them accordingly after indexing the nocks to the spines. If not, I'm always willing to learn something new and we're definitely on the right website for that. Regards, Jon [/QUOTE]
