OK, in keeping with the original theme of things...
Shimano Curado. An awesome reel. Could be better if they offered it in the 200 size and in a 6.3:1 ratio together. Also could be better if it had 2 bearings in each handle knob instead of only one, making it a 9 bearing reel, or even if 2 more could be added, I'd do it myself, but it can't be done. It would be slicker feeling for sure. I added a bearing to each knob of my BPS Extremes and they are now slicker feeling than before, and even feel slicker than my new Curado E7's handle paddles do. I know it isn't necessary but.....I WANNIT ANYWAY. ;D
Shimano Citica. Another awesome reel. Would be better if they had included the bearing on the inside at the end of the driveshaft, same as the Curado, instead of only a bushing. They could skip the bearings in the handles to keep the cost down, but the reel needs the one inside in my opinion. Not just for smoothing it out, but for wear prevention too. I'll be adding this to mine as soon as I order it. That's the single change I'd make to it without otherwise trying to turn it into a Curado. Basically, I think it would be nice if they offered both the Curado and the Citica with different options. Such as a Citica with oversized grips, or a Curado with smaller grips. Some people like features of each reel, and it's obvious there are those who are ordering parts and custom creating their own Citicados and Curiticas. I know it won't happen but it would be nice.
Shimano spinning reels in general. I like them but if you're gonna make an aluminum frame, go all the way. 1/2 of it aluminum and 1/2 of it graphite does nothing for me. I can live with graphite rotors, but both sideplates and stem and housing for the clutch bearings should be aluminum.
There are a couple of fishing items that I'd change NOTHING about.
The Abu Garcial Soron STX spinning reel. This reel is about as perfect as it can get. 11 bearings in all the right places, solid aluminum everywhere, frame, sideplate, rotor, and even the bail arm connecting to the bail wire. Comes with 2 spools, both aluminum, one ready for braid with no backing required. Sealed Carbon Matrix drag. Brass gears inside, drive gear and pinion both. It's light weight enough to bass fish with and solid and rugged enough for extreme saltwater fishing. Offered in a variety of sizes, and it's NOT ugly to look at either. They left nothing out.
Then, also the Shimano Crucial rods. Particularly the spinning rods. It's about as flawless as it can get. It has the perfect grip for the way I hold one, a moderately sized foregrip which is where I hold it at, the hookkeeper is positioned up the blank out of the way so I can keep a couple of fingers directly in contact with the blank and have a lot of clear blank to be in contact with (unlike on the Compre spinning rods with the small cutout in the foregrip and the hookkeeper too close to the grip as well). There are also no exposed threads on the Crucial's handle at all when the reel is seated down. IM-9 graphite blanks, Alconite guide rings, very light weight, and beautiful to look at. Shimano Crucials are perfect in every way. Pricewise, they are worth it too, but......just recently I discovered the Lew's Speed Sticks and they look to be just about as good for less money. Lifetime warranty and all. There are a few tradeoffs compared directly to the Crucial, but not $30 worth which is what the price difference is from the Crucial to the Lew's Speed Stick Tournament series. The Lew's rods look basically like Compres with better handles in terms of features of the rod as a whole. There is also a cheaper version as well, the SG series. At way under $100, it's about as good as it can get.
Drifted somewhat off topic, but not too bad.
