Super tuning varies from angler to angler. I like to take down the whole reel and clean all the factory grease and lube out of it. Soak the bearings in acetone until all the factory grease is out of them. Then take the spool bearings and put them in a cup and put 1 drop of oil on each side. Then, all the gears I make sure are packed with grease. Some say a little goes a long way, I like mine to be well lubricated. If you have never done this before, make sure you keep the paperwork for the reel handy so you can use it if you lose track of the parts placement. Another option is to send it to DVT, and for a good deal he can do it for you. As far as parts you can use for the G from the E. The only thing would be that you can take the crankshaft bearing from the Curado E and use it to replace the bushing they use in the Citica. Just so you know, you could take the Citica out stock and beat that thing all day long and it will take it. Dont be fooled just because its a G. They still are great reels. Shimano is just putting the reels back to where they should be as far as options/price lineup. When I relubed my Citica G, it was like night and day. Im gonna honestly say that the Curado E is going to be known as the best Curado that Shimano has ever produced, due to the amazing features that Shimano put in it. Unfortunately, since they had to make the adjustment to put it back in perspective, and let the Chronarch take the reigns again, people are set on the E, as am I. Since I own all of the E line up (except for the Chronarch 50E), I will be adding a Curado G to it as well. Ive used it, and I like it, and will tune it my way.
