Making this thread really because im interested how people do them here. Personally I do them but theres a variety of ways they can be done and people swear by doing it this way or this way etc. So how to do them to best effect in terms of hitting the lats. I've seen a lot of ways for example some people have their hands quite far spaced out but not fully, some have the widest grip possible on the bar and some people always keep their body still and pull down to their chest whilst others will lean back and pull to their chest.
So whats the best way of doing it? Some examples of what I mean from different ways of doing it and possibly not as good methods:

Anyway at my gym, got the same bar as ^ and I will usually do it (due to having long arms) with the widest grip possible.
