I like the 10% ordnance gel better, but the Clear Ballistics does seem much easier to use.

It was a fair test form what he demonstrated, the reusability of the Clear Ballistics makes it worth the efforts and repeatability.
I would trust the results of the Clear stuff, I could imagine the FBI might even consider switching their test criteria based on the repeatable results, ease of use, product stability and cost factors...It's a great product!
Thanks for the video post IC!

   If I were looking to buy a block it would be the clear due to being Synthetic. The shear fact temperature doesn't affect it is the big seller. All the other advantages are icing on the cake!
