The 12.4 has lower deflection due to the front end mass correct
Reflecting on deflection might affect perception or spread deception.
I've played about an hour(total) with both Revo's. Couldn't tell any difference in playability. Pick the size that feels right and go. I have long fingers and for me the 12.9 just felt better.This is absolutely the opposite of everything I have heard. Many people have opined that the 12.4 has slightly less deflection due to lower front end mass.
Your post smells strongly of someone with an opinion making up "facts" to persuade others to hold their views.
