Does anyone use the CWS supplements? Do you like them? I'm considering them as a potential solution to my desire for pre-illustrated pages. I've been busy adding stamps to the 1968 Citation I purchased a couple months back. For the late '60s to about 1980, I'm considering the CWS 1960-1980 supplement or finding a late '70s to early '80s Citation since Harris seems to have a habit of heavily covering the decade or so before publication. The latter would get me some pages for that year range and another big binder, which I'm going to need. Plus I actually like the enormous heft of the Citation binder.

The down side is that of the pages, I'd only want the later years as I have an older Citation already.
I'm not sure which of the CWS pages or a Citation of that age would have better coverage of the '70s, or if they'd be about the same. Anyone have any idea there?
I've read some people saying they prefer the Harris supplements to CWS, but old Harris supplements are hard to find. I can order the CWS supplements back to 1981. For the '70s, other than that CWS 1960-1980 set, it's trickier. It looks like it comes down to trying to find albums where someone previously added those years. I'm finding that difficult. Even when I see an album for sale online that might be a candidate, it's often hard to tell exactly what they did for the pages. If pictures show some pages from the '70s, are they from supplements? Were they moved there from some other album? Are they from a Harris Deluxe, Senior Statesman, Citation, or what? These have different levels of coverage. Do they have all the years? Many I've seen skip years, like one I saw recently that had some pages up to 1972, and some from 1979-80, but it had almost nothing from '73-'78. It also wasn't every country A-Z, but that's a different issue.
For countries that I want to focus on more, there's the option of making my own pages. I've been messing with Albumeasy some. I don't relish that for the entire world though, nor do I intend to spend thousands of dollars buying Scott International volumes.
