I like the photo. If you add my Soare Ci4+ C2000SSPG to that, you'd have three nearly identical reels there. With the exception of, as you mentioned, spool and shaft bearings for improved drag performance on light lines (probably handle knob bearing as well...). Funny, Cardiff and Soare are in fact identical with the exception of cosmetic features. My Soare is a sweet reel, as I'm sure your Cardiff is, too. I might also get Complex Ci4+ from that line-up – it comes in larger sizes, which I need for my "light" gear. I read a lot of great things about this lesser known reel.
One thing about Shimano's Ci4+ series: I doubt they will feel as "free" in rotation as Daiwa (I don't have Daiwa, I only had isolated encounters with it). I read the same a few times on Russian fishing forums. A few posts went as far as saying that you had to "get used to Shimano after Daiwa". With that said, the inertia is very low in the Ci4+ series, thanks to the very light rotor, so jigging and twitching is a breeze.
