I love poison cues and feel like they're really under appreciated. I have a poison cue as my player and one as my breaker.
I think the poison is a great breaker, but the shaft is a Venom2 shaft exactly like my player, which means it's somewhat low deflection. I think low deflection isn't something you'd really want in a jump cue. I mean if you know how to jump, it'll work, but it isn't really ideal. I can't seem to jump underhand very well with the jump portion. It feels like the weight is in all the wrong places. Dart method is manageable.
If I had to compare it to the player's hxtp1, I'd say the poison breaks better, but the player's jumps better.
