Thanks for the explanation Paul, as ever, I’ll bounce a couple of things back to see where it leads.
I lift weighs and I lift the same weight with each arm. If anything my left side I believe is actually slightly stronger. So I think it’s a coordination issue (and to a lesser degree a sighting with dominant eye issue).
I couldn’t tell which side of my body is stronger. Being a leftie, I probably spend a lot of time doing stuff with the wrong side of my body because the world is built for right handed people. When I switch sides, my movement accuracy is poor. It may be that we are trying to compensate for the lack of accuracy by using more acceleration to get line speed. If you want to do a speed accuracy trade off experiment on yourself, try writing with your wrong hand. Few of us find the mass of a pen an issue.
Science seems to indicate that what is commonly called muscle memory can be attributed to 2 effects, changes in the brain and the nervous system:

My takeaway is that development of both of these attributes looks to be dependent upon well designed practice regimes.
I actually think Steve’s forward cast is much closer to the wide arc we used to apply and our wide arc is now narrower (as a consequence of using stiffer rods), so the differences are not that great, if at all.
I used to think that I could avoid damaging my shoulder by using a narrower arc like Steve Rajeff but it seemed to me that he opened his arc on the delivery stroke only (bc/fc) which would still cause the hyperextension that I was trying to avoid.
There are two reasons why the 170 generates higher line speed on the backcast. 1) we apply far more force with the rod – and through the point where the OSD BC normally stops and 2) the hauling is considerably faster because it’s the separation speed of the hand and stripping guide.
Is this additional back cast speed real or a construct? We are not designed to throw backwards, so I struggle a bit with the concept, unless there’s an advantage in the bc haul that I haven’t seen.
With regards flylines the advantages of stopless start to disappear and with short heads. Indeed the 170 “works” because while we pull more line away from the target, the line that is left behind at the top of the loop, is long enough that it sets the trajectory. Of course you can carry more overhang with stopless but I’m not convinced that maximum overhang on the backcast is always the best way to throw distance on the forward.
I’m interested to hear from the wider audience on these statements. If distance is related to carry, are you saying that the 170 is the answer to carrying a long head? The overhang on the bc seems to contradict the earlier statement on bc line speed. It doesn’t gel for me
