OK, I did this with a different string. The old string is a hybrid 3 bundle 9 strand. 2 strands of Rhino, and 1 strand of 450+ each bundle.
The new string is a Bloodline Fibers Brave99. It's a 21 strand 3 bundle 7x7x7, with the loops padded to 30. With all the silencing stuff added it still weighs 35 grains less than the old string set up the same way.
The arrows flew like wet noodles weak with the new string, so I footed them with 2" of GT Trad 7595 to stiffen them up. It worked out quite well.
 With the old string, I had my sight zeroed at 15 yards. With the new string that zero is now 30 yards. Yes it is that much faster even though the arrows now weigh 22 grains more. Went from 627 grain (9.6 gpp) to 649 grains (9.984 gpp). Remember now - I'm using a sight. 30 yard group before fine tuning.  30 yard group after fine tuning.  My center shot adjustment with the old string & arrows was +3/16". With the new string & arrows it is +1/16", which is right where I like to be. Now all I have to do is foot the rest of my arrows, and rezero my sight for 15 yards. It's still to cloudy, and rainy for me to get good chronograph reading, but I'll do that at the first opportunity. |

And, here's a speed test done by AMO specs.

Side note. It's way harder to intentionally short draw a bow to a consistent spot, than one might think. The draw check did it's job. Bumped the arrow off the shelf once, and pulled it off the string twice. No way to shoot the bow any way other than at, or before that draw stop. It was scary though. I was scared to death I was going to dry fire the bow. Made it through it though, and now I'm done with that nonsense.  |
