I cannot comment on whether the Shimano Poison Adrena 7'3" MH Reg/Fast rod is suitable for swim jigs or 1/2oz chatterbaits, as I do not use my Poison Adrena rods for those techniques.
However, I can address the claims that Shimano Poison Adrena rods are susceptible to breaking during hooksets. While any product made by humans can suffer from manufacturing defects, I own two dozen Shimano JDM rods from the Poison Adrena, Glorious, and Ultima lines, and none have broken to date. This could be due to my meticulous care for rod storage and usage on my bass boats. It's likely that breakages during hooksets are more often caused by having too many rods on the deck and accidentally stepping on them, or boat flipping fish, both activities that exceeds the rod blank's stress capacity, rather than by actual manufacturing defects.
Indeed, these pictures serve as evidence akin to the original BBS days, suggesting that I may possess some experience in this subject matter.

Shimano 22 Poison Ultima 170MH, perhaps the finest JDM bottom contact rod Shimano has ever made period!

As requested by someone on the TT forum, here's a balanced view of the Shimano 21 Antares DC reel paired with the Shimano Poison Adrena PA1611 M+ casting rod, which is the most versatile PA rod in my collection.
Good luck with your swim jig and chatterbait rod search!
