It is clear on here that this group is anti AEV, and from what I can tell, pro EVO.
As to, when does flex become a negative, when your tire drops too far in a hole and starts to work against climbing a boulder, going up a ledge.
Suspensions installed, Teraflex, Rubicon, and mix match pieces.
I thought this was a solid forum of information, but clearly it is one sided.
My jeep works, Utah, Cali, Colorado, New Mexico, pleased with each aspect of it.
To each there own, I'm sure I will see some of you on the trail someday, till then, enjoy your forum, and happy trails.
