I have recently uploaded 5 videos onto Youtube, of various stretches I have been playing around with for the lats and their associated soft tissues and investing fascia, and of the Lateral Line (and the 'Deep Lateral Line' connection of the QL --> Diaphragm --> Mediastinum --> Scalenes; if you are sufficiently body aware and supple already); Back Functional Line and Spiral Lines (using the myofascial meridians terminology of Anatomy Trains - see 2nd edition of the book for the fascinating details).
I had started to play around with different vectors of stretching the lats (and 'sides' more generally) when I had access to ladders bars for training (I think a lot of people stuff around hanging off ladders bars when they are available..there's something natural and human about it).
I was talking with Simon Thakur, a while back, about 'Opening up, strengthening and becoming more aware of the 'sides' of the body - and lateral movement, especially lateral spinal waves and undulation' which led me to explore this fascial and neuromuscular stretching (soft tissue remodeling) aspect some more.
Here are the videos:

The 'basic' side stretch can still work wonders on more advanced practitioners, if they have the body awareness and micro-movement control of the spine - aiming at as pure a lateral flexion as possible.

Besides opening up the often restricted coronal/frontal plane of movement, these techniques remodel the soft tissues over, around, between and inside of the ribcage - thus freeing the breath*.
Along with specific breathing pattern and diaphragm work (pranayama; qi gong; butyeko; etc) this can tangibly increase, not only the movement capacity of the body, but the sensations of being alive and offers numerous health benefits, too.
You can also get into the 'poplar tree' of the various 4th layer(? - iliocostalis group; etc) back muscles via adding different spiral vectors and directed breathing techniques - which is great, as these muscles are notoriously difficult to isolate in stretch.
Once you get a feel for how the greater tissues of the latissimus dorsi can be wound-up, you can create numerous variants which can be done off just about anything upright that is stable (pole; doorway; tree; etc), to varying degrees of success.
Spirals!Spiral vectors from the legs, trunk and arms work very well. Multiple spiral vectors works even better. You can 'play them off against each other' and wring the adhesions out of your soft tissues. Interestingly, the latissimus dorsi (and pectoralis major; among others) has a twist (spiral) in the morphology the muscle.. perhaps this is why they feel so good to twist like a wet towel?
For me personally, the feeling and observation of how the lats, pecs and traps get involved in the straight arm gymnastics holds (especially when you are strict with keeping the sternum up; so, not holding for maximal strength, which uses the hollow shape, but training for max strength-control from a position of postural alignment), I have wondered if what was happening was that I was learning to use the lats, pecs and traps, in essence, as a 'secondary rotator cuff' - by training them to stabilize and control a straight arm in various positions.. not sure how accurate this is, but a tangible re-patterning of the muscles occurs when you learn to do straight arm work ala gymnastics, and various other holds, in combination with traditional concentric/eccentric work - or at least this is how I experienced it feeling in my own shoulders and arms.
This alignment (upper thoracic extension/sternal lifting with scapulas allowed to move down the rib cage) is often not possible for a person to maintain on the rings or paralettes for very long, or at all (or even in daily life, for some).
This is often related to daily postural and movement habits. Sitting in a chair, and having the usually things happen (tighter hip flexors; collapsed ribcage and diaphragm; hyperkyphosis; scapula coming forward and around the rib-cage; etc.) tightens the latissimus dorsi in a specific way; and predisposes you to use only a discrete sector of this massive and variable muscle when you do you strength training exercises.
This discrete sector is usually the over-facilitated sector anyway, and leads to thick ropey strands appearing in the lats as vectors of force have connective tissue laid down in their paths. I have observed this a number of times with people into strength and conditioning work; boxing and other sports involving repetitive pulling. Certain fibers of the latissimus dorsi are heavily preferences due to scapula position; rib-cage angle and spinal curves (obviously, and especially, thoracic). I am sure it is not everybody, but it is an interesting pattern.
Finally, on stretching longer chains of fascia and connective tissue more generally, I have found that these long chain stretches respond well to a number of different methods - other than just standard contract-relax (PNF), as emphasized in the beginning and intermediate stages of Stretch Therapy classes.
Some of the 'enhancers' I use are:
• Mirco-movement exploration (lots of different easy to more difficult vectors - simple sagital plane work; rotations; figure 8's, spirals and waves)
• Directed Breathing (especially for muscles/tissues attaching to the trunk and ribs/abdominal area).
• Outside Support (Tractioning & Bracing via partner assist). This often uses a belt (judo belt or fabric sash for comforts sake) or manual assistences.
