Tall and Fall or Drop and Drive

As a sidearm pitcher, should I use a more “Tall and Fall” delivery or a “Drop and Drive” I have had a few people look at my tape and say that i am using too much arm and not enough of my lower half when throwing. So, if I use “Drop and Drive” will I be more effective?

I think it all depends with which u feel more comfortable with and makes u throw strikes more. I stay “tall and fall” because i think it makes it easier for me to throw strikes. I have tried to change to “drop and drive” but just cant make the adjustment and be comfortable with it. Ive wondered if it Is okay to stay tall and fall…I hear it wears down the arm a lot more but is it alright to have this approach?
