The problem the series had when it first came out was that the levewlind stuck, there wasn 't much space in between the line guide and the worm gear cover, problem that was immediately dealt by Shimano by sending you a repair kit.
The 100 size Curado D was an improved version of the old trusty 100 B ( lighter, lighter shalower spool, metal cast control knob, metal drag star, speton grips ) the 100 DSV had the same improvements but with the deeper spool identical to the one found in the Curado 100B.
The 200 size were really good reels and were more comparable in features to the old Chronarch than to the previous B series. I have a Citica 200D ( same dimensions as the 200 Curado D series but with less features ), nope, the reel is not larger than a 200 Size B series Curado. Putting them side by side for comparison the only difference in dimensios is the slighly longer length of the reel because of the pointy front end, what makes it look larger is the big HEG gearing housing on the handle size, this does not interfere with the palmability of the reel, the "bulkiness" is apparent, but not truely real, what makes it feel bulky is the weight, weighting nearly 10 ounces is far from being the lightest modern baitcaster out there.
