From my experience, this is the worst option. First, there are 2 TCs you cant push through instead of 1, also with good scouting or just naturally 2nd cuman TC can be on stone, so its lower possibility to push off stone. And then you gotta add that cumans have +50% on pallisades, which helps a lot vs any feudal aggresion + theres a possibility to get pushed by rams, although huge investment for feudal can work very nicely vs trush+maa in late feudal.M@a + towers or full trush should work I think
