My Pings kept "bouncing back" after each attempt to bend them so I baught new clubs
I think the "bouncing back" is a symptom of the way ping heat-treat their iron heads. I don't know who was doing the bending for you, but if it's someone local and you really still wanted to play your old pings, then I believe that Ping can do some special magic in resetting them if you send them back to the factory.
What about the sole angle at impact? Are your new flatter irons now flush to the ground at impact as well as helping your path, or did you need to compromise your lie angle in order to get a better path?
If so, I guess that sounds a warning about even a dynamic fitting. You could get a perfectly "fit" club according to a lie board - which nevertheless screws up your path.
