Only slightly negative observation would be about putting everything in chronological order, as in semi-postals, airmails, etc. The Minkus catalogues did that, which I have found irritating when I've bought collections on Minkus pages. I like having the B-O-B separate by category.
Over the upcoming holidays, I'll be completely re-doing my collection of Poland. Not sure yet of the plan, but know for sure the Part 1 International pages won't be used. So, many blank pages, a combination of Subway G & K, and trimmed down blank Specialty pages will be utilized.
My plan for now is to leave volume one as a separate entity and then to collate the rest. I just bought a volume 7 to take coverage to mid 1971. I have a large general Russian collection that will be remaining on Specialty pages so not having the Russia pages in the mix for the Internationals will save some binder space.
What works for one guy, doesn't work for the other, and the third guy is doing something else altogether. That's why they make chocolate, vanilla, AND strawberry. And why Baskin Robbins has 28 other flavors.
