Dick, I have not ambition making you change from your habitual playing to something you strongly indicate that you would not like and this goes for anyone else.Changes at best come from inspiration or curiosity not by force.Some changes do come by force, not least legislation, and certainly it happens that some of these after a while are 'comfortable' and willingly accepted, or even understood as being "self-evident". That happens throughout history.
Your arrangement works for you, fine,but it does not say that it is ideal för someone else, not even for someone playing the same music as you do.
IF new handles and methods may be found beneficial for a wide musical spectrum a lot is gained for the general population of players and there really are several indications that the traditional handles - both the Anglo/Duet and the English concepts - are not ideal for any musical style of performance. This is hardly a matter of individual opinions - it is a matter of learning, knowledge and not least of open minds and some curiosity to try something different.
Conservatism can be a wise strategy in many aspects - out of say some thousand innovations maybe one or less turns out being successful in the long run - but without trying nobody will know and no progress will ever take place.
