I have shot a Predator exclusively for over ten years now.
I have a spare set of duplicate limbs in the weight I am currently shooting. I can interchange them and not notice any difference.
I have untold numbers of arrows through it. I couldn`t even guess how many.
My advice is keep your arrow weight around the usual ten grains per pound of draw weight, get some quality string silencers, and have a ball.
If you are like me, you will find the bow easy to shoot, and will notice your shooting improve instantly.
The lack of hand shock with your Predator will reveal just how much shock some other bows have, that you never even realized before.
Congrats on your purchase...you`ll not regret it.
