I don't see myself straying from Shimano reels any time soon. While not "old" by some standards, I have a Citica 201D that has never been opened up, except for some oil on the worm gear and spool bearings, and it is still smooth and quite. IDK if it's just me, but Shimano reels don't often feel the smoothest new out of the box as some others, they seem to have a " break in" period, but they sure do get smooth, and stay trouble free (if you take care of them) for longer with less maint. than any other reel brands I have ever owned. Just the opposite in my case were Daiwa reels, best feeling reels straight out of the box, but were very fussy with what oil I lubed them with, and performance generaly faded with use. I am not talking super high end Daiwa stuff, but not low end junk either, and I had enough of them (TD Fuego, TD Advantage, TD Tierra, Exceler) that acted the exact same way to think it was just how they where/are. Pure fishing stuff (Abu/Pflueger) treated me a little better, I don't have a bad thing to say about the Revo's or Presidents I owned.............there only problem is they are not Shimano's LOL. I have never had good luck with most big chain store branded stuff, at least with reels. I don't have any thing bad to say about Gander Mtn, or BPS rods, owned a few and they were fine, but, like the Abu/Pflueger stuff, there problem is they are not St Croix's, which is my prefered brand, but thats another topic. And...........this may surprise some people, the reels I like best and still keep around and use besided my Shimanos are Quantums. The oldest and most used/abused reel in my boat is the previous generation Accurist 501PT, it's a tank. 50lb braid, on the flipping stick, drag locked down, never been opened up, just cleaned off and oiled. Finish looks like crap, but I'll use it till it dies. I also have another, with 50lb braid, on my frog rod, same exact reel, just not as old. NIB for $50 on ebay........can't beat it, will also use till it dies. Both of these reels have gotten smoother/better casters as they age too. When they do die, I probably will replace them with Shimano's, but I will think about Quantum if I can find a deal on one.
As far as the new Shimano line up goes. I can't wait to get my hands on one, but being the cheap skate I am I will buy the G series Citica's and Curado's when they go one sale in the future when the H series comes out. Givin Shimanos recent history that should be in about 3 years LOL. I have also never seen a loss of performance, quality, or value when they change series, IMHO, they know better than to try and pass off inferior products as new and improved. You wait............I have seen it every time they come out with a new reel, people always complain that they won't be as good as the last, but every time, they end up being better.
