So i am always getting countered when i throw jabs... tips? I almost always have reach advantage.
counterd by left hook
That means either you're not bringing that right back fast enough, or you're dropping your right when you bring it back, or you need to bring up your jab so that your bicep covers your chin when your arm's fully extended.
You don't need to punch down if you're tall. That's a myth. What you need to do is lower your elevation slightly and jab normally. Being as you ARE tall even if you bend your knees sufficiently you should still hold a height advantage. I'd wager odds that if you're punching downward then you're leaning forward to do it. When you lean forward you bring your face closer to the other guy, into his firing range. If you need to get close you move your feet close, you don't lean. And if you need to hit a smaller guy you bend your knees, you don't reach down. If you need a reference, check this out:
Note the angle Vitali jabs at. He bends his knees a bit, and his jab comes from under Adamek's line of sight. Which is why he had so much trouble defending against it. In contrast the right hand comes downward, but he doesn't lean in far and compromise balance to deliver either punch. In that fight the one moment he did compromise balance, he fell over. If Adamek would have thrown a punch right then it would have been counted a knockdown.
The key difference here is as a Southpaw, your right jab should travel either over their right hand, or right up between the gloves, depending on how they hold their hands. Your right shoulder should be defending you from hooks, at least up to the cheekbone. But if you're reaching then your head is likely coming up and being fully exposed. Keep it down and a hook should bounce off your shoulder.

If the guy is punching downward and leaning, I don't think his fundamentals are good enough to do all that other stuff.
