I always strive for as good as form as possible. I want to hit the muscle group I'm working.
I actually like a lot of cable moves. In fact I like more cable work, than DB work. Low pulley rows for lats has always been one of my favorites. I've rarely actually had a low pulley machine to use. For a long time I used a universal machine and improvised.
I used the low pulley off of that and put the lat bar on it. then used a block of wood as a spacer, and foot rest. This moved me back far enough to get a good stretch, and rowed. Worked great.
