throw tech trapping stuff
Honestly, unless your someone like Astaroth who has monstrous damage off of his throws you shouldn't be using throws as a techtrap.
In a few of the instances you listed above you sacrifice guaranteed damage so you can get a 50/50 throw attempt that is easily punished if the opponent doesn't tech, or lays on the ground. Its better to go for the guaranteed "little" damage, than risk a massive whiff or if you guessed correctly and caught them with the throw, have them break it. However, if it works for you then keep using it. Just keep in mind the faults in the strategy.
