RE: Mechanical release shooters should or should not bare shaft tune?
I whole heartedly agree with Arthur. Bare shaft tuning works very well with a release, better so than paper tuning in my opinion. Just like paper tuning you can't expect exact results out of a certain adjustment when using a release. There are no set rules like when finger shooting.
Most of the time the conventional things apply for me though. However every now and then you may have to make the opposite adjustment to get the desired results.
