    Throwbag-suggestions for 1.5"-wide Air-Cannon usage? (*besides* Weaver 12oz!)

    So I've made a "generic" 4' long, 1.5" thick PVC air-cannon, thing works well enough so far as I can tell but I don't have a proper throw-weight for it!! In reviewing others' cannons, the two most-recommended bags are: 1 - Weaver 12oz, and 2 Stein 14oz Would greatly appreciate more options...

    Home made rope spool /rewinder. Great for 80' and under, but can't keep up with high speed 130'+ launches.

    Tied my rope to the 150 foot throw line. The bag went up beyond 150 feet, and started pulling rope. As it settled, and I fed it rope, the knot caused thing to pause- so the limb was about 148 feet! Not a strong enough treetop to climb, but fun to test with.

    New Revision 10 launcher, Throw bag test. (Arborists)

    Ok, I want things to be apples to apples, so I bought a Weaver throw line kit with 2mm line and a 16 oz bag. The New Rev. 10 launcher, with a tiny 18" barrel I had for fishing.
