All my cues are poison. I play with a poison ar2, and I break with a vx4.
That being said, I hate the way the vx4 jumps. The poison jump cues I've tried, I would say are better than the jump break, but not by much.
If I had to choose between the two, I'd get the air 2.
Right now I'm trying to decide between the air 2 and the jacoby jump cue with extension which is a more difficult decision.
You will be more happy with an Air 2 than a poison, as much as it pains me to say (I really like poison)
