> We feel the need to apply momentum most strongly on the really small holds. There is no other option to initiate the next move. However this momentum,. and the dynamic movement that accompanies it, should also be applied even on the bigger holds, where we could do the move statically. The reason is that momentum produces efficiency. Less force is needed at the fingers and more of it comes from the lower body or momentum of the body mass that started from a lower, more advantageous position for generating force. Thus more upper body strength is saved for higher up the route. For this reason, momentum should be used on nearly every move.

To me that basically sounds like he's referring to things harder than a VS. As for practicing falling, I would do that indoors on an overhanging wall and not outside when trad climbing up to VS having fallen and broken my ankle myself leading a severe.
To best execute a movement with what you've got is different from everyone else. Personally, my advantage in height can mean I can occasionally skip holds that I find too strenuous but in turn others can be made more difficult (like when climbing overhangs). I work on these problems to become more confident at them doing pull ups and bouldering short overhangs on good holds to practice the technique and movement I need to execute to get up an overhang.
My favourite is practicing climbing with no hands.
Get a slabby wall and walk up a grade 3 or 4 to the top. No using features, or holds, or edges with your hands; just place them flat on the slab and smear. It's amazing how much you can trust the strength in your legs afterwards and reduce the strain on your arms when climbing harder grades.
All my training is done on an indoor wall but I find it really does help with outdoor trad (I climb up to VS).
