I like to go the faster build in 1vs1 as well.
It forces enemy to go skirms.
You need to use the timings and be agressive early.
Once he add and upgrade skirms, then you go back and literally wait till castle age to attack again.
The bigger mass you have the better, once you are in castle age you can play normal game.
TCs, knight + xbow, xbow + monk, xbow + siege.
This build is fragile and pre-mill rush is hard on you.
Scouts are stronger because you cannot afford spear.
Walling is expensive but a must to play this tactic.
Once you are walled you can play around that with lower mobility.
The biggest spike is in castle age when you have big ball.
