So today I went to my buddy/neighbor/co-workers house for some shooting around. He says if I'll come by more often he'll put down the training wheels some, or even mostly, this year. Yay!
But back on topic, he gave me a 300gr FP to try. My Grizzly Sticks already weigh 646gr with a Nockturnal. These put it around 826! But to be honest, there wasn't much flight difference, but it did help the sound of the arrow in flight. The sound of the feathers was hushed a lil bit, as was the sound of it being loosed.
Obviously I did lose some speed & elevation from my already slow bow, but man did it feel good. And by good I mean, quieter than the brand new NoCam he was shooting beside me (with ABHS Momentums!). Even a bit quieter than his custom Flanagin recurve!
