Could you give me the pros and cons of both lobbing and throwing the projectiles and which is the best technique?

The Mortar Throw vs. The Cannon Throw

who will win?!?!?

All guess what is my position. 
When I was a little boy, I fell in love just sling force.

I like to do both depending on what my objective is. If I want to drop a rock on top of something then lobbing it is. If I never want to find the rock them I throw it. There is a happy medium to though.

Not to be a nitpicker,just longest shots would be about 38-40 degrees for a nice lead gland. Depending on sectional density and aerodynamic properties.

Though the lob has its place, like in a target shooting competition,  I like to pulverize my target.  Most times I'd rather throw, hard.

Throwing all the way for me. I'm actually less accurate if I lob because I'm not used to it.

You can read more about it in the thread we just had here http://slinging.org/forum/YaBB.pl?num=1383243780

But seriously-- learn to lob, too. It helps with shot placement.

This summer, I was shooting straight at my usual target and missing, at 23 m or so. And we're talking a very large target. Then, because my arm was sore, I lobbed, and hit it plumb in the middle. The next five shots I lobbed, and they hit the same spot. It almost felt like cheating. And these were not weak shots, but involved egg-sized things dropping and shattering against the cliff face with satisfying cracks and puffs of stone chips and dust.

When I said lob, I meant the thing you see in all of these target competitions y'all post where they throw it like a panzy. My stance is that a sling is a weapon, not a game of cornhole  .

Power and strength make a weapon. However I see a lob being useful in the ancient military. When groups start closing, rain mortars on their heads; however, they probably lobbed it, just with power. Throwing it strong and high.

By kinetic energy, a lob should be the most powerful attack, if thrown with force. In parabolic trajectories, the maximum force/KE is at both the starting and ending points. Anywhere in between is less force and the closer to the center, the less force. But when you throw it like a three year old, no matter how parabolic your trajectory is, it should hit with the power of a 3 year old's sling throw.

I had my answer before I posted this, I just wanted to see the general opinion on this.
