How good you are at teching throws depends on the person and their mindset. When you get hit you think oh god a combo, mash tech. Or you can think, a combo - look out for resets (Try to remember if anyone has done it before), care of purple although it doesn't happen often and teching correctly.
Obviously throw techs get better at the more you play, some people can start off really good at it, other could suck completely (me).
You should always watch out for Tao Purples near the end of her combo, she does it for positioning, just don't get hit by it. Carl has a purple grab unblockable thingy on Tager too, nothing you can do about though.
I actually used to play Lambda in CS1.
