Yes, BOTH at the same time, I tape modded my new style flatline to accept my Apex 2 tip. And the amount of curve is INSANE!!! I call it the MonsterSpin system.
How about dive bomb shots at 60 FEET! Imagine having this on a speedball field, no one could hide in the snake, or behind bunkers, and you can adjust it easily for longer shots!
And here is some "flat" shooting with both systems set for flat shots. If you have used a backspin system before, they create a "speed wobble" that you can see when the ball exits the barrel, well, by using BOTH systems at the same time, those wobbles go away and you get a more consistent shot. Pretty cool!
