I have a few tweaked (modified) removers by now, but still need one for a Campag 2-prong alloy FW.
There are a lot of different freewheels, gad!

Sometimes I'll "dress" the freewheel and tool prongs with a Dremel to improve the grab if the freewheel is very tight or the tool fits poorly.
Again, the smaller freewheels usually require much less force to remove.

I always sucure the tool TIGHTLY before torqueing, but must loosen promptly to continue turning as the freewheel backs off.
A longer wrench, like 18" or more, puts less sideways force on the tool for a given torque, which helps it stay centered, and a vice is even better.
I find the job is easier with an inflated tire mounted, for grip against the ground or for hand-gripping.
