I have over four dozen various Shimano reels so you can see where my allegiance lies. Anything from a Curado up through the Core (discontinued), Chronarch series, Metanium, Aldebaron and Calais - changing out bearings is a waste of money and time. Shimano is known for their bearings which really are second to none. If you have a slightly lower grade reel in their line you might notice a difference. The spinning reels I have are the Soros, Stradic, and Sustain, all of which I'm happy with.
As far as the Poison Adrena - I do not have one but do have some Exprides I have been very pleased with - extremely light and sensitive and many actions to choose from. I also have the GLoomis NRX rods, the IMX and the EX6 series, the Shimano Cumara and Crucial rods. They each have a place for a technique. And I certainly won't spend $500 on an NRX rod fro crankbaiting. Had I not had super pricing on a few of those I wouldn't have spent the money but they are a dream to fish with. I am very impressed with both the Shimano Exprides and the GLoomis E6X rods.
