I always use a Stop, but I consider them a piece of equipment that one has to learn to understand.
#1 Beware worn bobbin assembly and new rope, a deadly combination.
#2 Always pass the rope through a carabiner attached to you harness D maillon in the same way as you would a simple bobbin descender. This enables you to easily lock off, you CANT rely on the autolock, see #1.
#3 NEVER attach with an oval maillon, it can twist against the gate and cause the Stop to open. A D maillon is OK, if you dont trust a crab which can fail if loaded on the gate somehow.
I have been using a Stop for over 20 years and the only issue is that my left hand aches on long pitches.
