subjectivity alert!!!!!!!
I have tried the brick and the Lomax jump cues. I thought they jumped about the same. Mainly just trying to find a good cue that breaks really good too. I haven't tried the bk2, poison or Lucasi air hog. Those seem to be most popular.

this is always going to be subjective because, as you know, some like chocolate, others vanilla.
with that said, if you do a search on this subject you will see that the two consistent leaders for a dedicated jump cue, and with good reason imho, are the Jacoby and the Lomax jumpers.
These two are strong!
I have both and for when balls are close to jump I use the Jacoby because it has the groove to using the dart method. This feature is helpful because I have a bum right shoulder and getting into position for that close jump shot is tough using the conventional method.
I have heard good feedback on the colorful poison jumper and, believe it or not, the $30 J&J does a great job, too.
But overwhelmingly, it's Jacoby and Lomax. If you do the search you will see an azer (I forget exactly who it was), did a very in-depth review of the Jacoby and thinks it's the best ever.
Here's another subjectivity alert for you:
For a dedicated breaker, it's a bk2 with either a white diamond (phenolic) tip or a Samsara (leather) tip.
No other breaker matters, they will not move balls more than 6 inches.

:grin:
the bk2 will crack the balls in half.
gl with your decision.
best,
