I agree with Phil. Unless the arrow is severely underspined - like a kiddy arrow spined for 20 pound bows but shot with an 80 pound bow w/high performance cams - it's not going to blow up on release just because it's underspined. No way. An arrow that blows on release was most likely damaged OR was flawed from the factory.

I've had wood arrows explode on release. I've had fiberglass arrows blow up on release. I've never had an aluminum arrow blow up. Because of my experiences in my younger days with wood and fiberglass arrows, I learned long ago to check my arrows before putting them back in my quiver, so I've never had a carbon blow up in the bow, but I have seen 'em do it. Fortunately, none of the instances I've witnessed have resulted in anything worse than extreme string rash on the bow arm. One guy had a nice black, blue and purple welt on his bow arm, from the middle of his bicep clean to the heel of his hand![:-]

Guys who refuse to accept that their beloved carbon arrows can be dangerous are living in a fantasy world and could very well be posting their own pics on the internet someday. Don't let their unbridled and misplaced enthusiasm for carbon arrows mislead you and confuse the issue. IMO, it's not a spine issue that's causing arrow failures with carbon, it's undiscovered damage or factory flaws.

Doesn't matter what material your arrows are made of, carefully check each arrow before you shoot it. Every shot!
