One more thing you might try before you dump the savage is setting it as tight (quick) as you want, where it barely or not hardly will support the arrow. Attatch a cocking lanyard to it like you would a trophy taker or something. You' ll never have to remember to cock it and it might give you the adjustment you think you' re lacking to find the " sweet spot" .
We use this setup on my sons bow and it works fine and addresses a few other issues as well.
1. Like I mentioned he doesn' t have to remember to cock it.
2. His bow isn' t cut past center, but we can shoot the cock vane out with this setup.
3. We have the forgiveness of a fall a way and he does well with most arrows we' ve ran through it, including those suited to my bows (and he draws 25 lbs at 21" ).
4. If he creeps forward any his rest doesn' t start to fall, the magnet stays engaged. No major fliers. He' s still growing into the shortest setting on his bow.
5. I got the savage out of the archery box and put it to good use (I don' t like having decent accessories not being put to use.)
6. I used to use a fallaway and if it is good enough for me, it' s good enough for him.
Just a thought anyway. Good luck!
