Same here, if I see a nice cat, the carp become an afterthought for a bit. And it only takes about a 5 lb channel cat for me.
Hits twice as hard...to me that means twice as much KE. 1/2 mv^2. Meaning, to double energy (twice as hard) you need sqrt 2 times the velocity with the same arrow. That is, 41 percent faster velocity.
That simply is not happening. A 135 fps fish arrow from an osprey is not turning into a 191 fps fish arrow from an AE at the same draw weight. Hell, at any draw weight.
Even if you are talking penetration (or in this case, double penetration :jd

if the bow and arrow is tuned really well for the shooter, it will penetrate well. If it hits the fish a certain spot, it will penetrate well.
Also, you are putting in to the bow whatever is coming out of the bow. If you think it shoots faster, it might be that it does shoot a little faster, just chrony it and take away the mystery.
I don't doubt it is a great bow, and anybody can say what they want (as long as it is not negative about a BFC sponsor), but I doubt the maker would be willing to say "My bow hits twice as hard as an osprey at the same draw weight, here are the chronograph results."
