Maybe look at your drag brake setting on the speedy. The more drag brake, the more the truck will want to nose down over jumps if you release the throttle. Obviously the higher the drag brake the more tendancy the truck will want to nose dive just as if you push the brake to nose down mid air. As for not jumping straight, maybe a shock has some rebound issues that causes uneven dampening off a jump. Try bleeding all shocks again and check rebounds left to right shocks, should be as close to same as possible.
