This is all pretty funny to anyone who has been in archery for a while. Every single word said has been said before about the march in weight down from 10 grain/pound arrows to the currents standards.

Well OK the IBO stuff wasn't part of the package, but what a joke to be talking about an IBO standard! There isn't any such thing. There is a rule relative to competition, but inlike the AMO rule, it doesn't specify any particular testing conditions, and is specificaly there to put forward a standard that isn't velocity based. There is absolutely no reason why HCA should use an IBO standard for anything. Anyone who wants to push the envelope into lighter than 5 grain territory, can't use the IBO or AMO standard, nor can they compete this bow in any regular 3D comps I am aware of. They may even feel there are legal reasons not to quote these standards for this bow since they are based on the idea that sub 5 grain is dangerous.

There has been a lot of tech change since we first moved into the 5 grain area. It must be possible to engineer a faster bow with lighter arrows. Sure it won't be very efficient with a lighter arrow, the same is true with 10 grain vs 5 grain. Since when isn't 70 foot pounds enough.
