In reply to Sabulhawa:
You will either not stimulate the muscles / tendons / pulleys / nervous system / whatever enough to trigger strength gains, or you will accumulate fatigue faster than you recover and suffer the consequences.
At your advanced training age you are right to consider mixing up training protocols to keep making progress in finger strength. But don't forget the principals; train hard enough to stimulate growth, recover well enough to grow.
Your first two hangs feel higher quality because you are stronger at the start of a workout than at the end (as you know). But the gains are not made in the early sets, they are made in the later sets.
