Lacrosse stick problem...?

I cant get my lacrosse heads to throw correctly. I have a clutch on a liquid metal and it works like a charm but i also have a Brine Truth and a Gait Torque, both good heads. Unfortunantly i cant get either to throw correctly. I bought my torque offline and got some guy to string it with 6d mesh and it looks fine and i just won my truth at a lacrosse camp the other day for being MVP =) ha but anywyas. I tried playing with both and both have a very low release, like if i throw over hand they both shoot straight down off the ground. I tried tightening the side wallstrings but it had no effect. I was wondering what the cause of this is and if i could get any advice i just don get it.
