Stuffing Carbons

[pcappy08]

i met a guy who uses hardwood dowels and they worked awesome for him could be very worth a shot

I don't know how much weight you are looking for, But try experimenting with saw dust, pack it down  with a small dowel.

Why not just go up to a heavier spined shaft with more weight up front? Thats whaT I did and got great arrow flight and better penetration.

Second the poly rope. After a few shots it compacts in the front of the shaft giving you a desired foc.

Personally, I would stick with the 10.5 GPP if its tuned well.
