I have tested this and in my testing, the heavier your system is- rifle, bag, tripod, the better it works on a bag on top of the tripod. If you get lighter with your rifle and keep a heavy bag, the bag still beats out the anvil. Once you go light on the bag ie gitlight fill, the anvil pulls ahead with clipping in. I don’t know exactly where the transition takes place but for NRL hunter style weights, the bag has been better for me. When I am actually hunting I clip in because I don’t carry around a 9 lb gamechanger.
This was tested with an rrs 33, rrs 14L both with anvils, and a leofoto inverted 2 section with their knockoff anvil with and without plates and gamechangers with heavy sand and git light fill.
Your experience may be different. I would love to read what made a difference for you guys.
Also, I did find the anvil to dampen wobble noticeably faster than the leofoto version although neither would have caused me to miss a big game animal at reasonable hunting distance.
