If you go to this faq page by Chris Juden https://www.ctc.org.uk/DesktopDefault.aspx?TabID=3808 down near the bottom is a question about half-stepping. Mr. Juden does not believe current derailleurs will work well with less than a 10 tooth difference in the outer chainrings. I was wondering if this was other tourers experience.

I experimented with half stepping two years ago. The ramped and pinned chainrings like Shimano would not upshift well at all for me, Then someone suggested I try plain Sugino rings and those worked much better but still required some finese when shifting under load. I think because the chainrings are so close in diameter the chain is more difficult to deflect to the next chainring.
The half stepping didn't do anything for me,I went to 9 speed last year and that brought the higher gear ratios close enough together that I seldom need to double shift to find a comfortable gear.

According to Robert Beckman and Rivendell, if you want half-step, a road double derailleur works best.
I had hafl-step back with my 21-speed bike, however, now that I have 27 speeds, I prefer to use a custom cassette which gives me results fairly similar to what I had with half-step plus granny, but with less double shifts. For instance, at some point, my tandem had:
48-38-24 and 13-15-16-17-18-20-23-26-34

I have a 22/32/44 on a road bike; however, I also could also have chosen 24/34/48 right off the shelf if I'd wanted a little higher gear (48x12). With this, I have Ultegra index shifting using the new 12x27 DA 10-spd hub.
I had the complex, down tube, double shifting arrangement that you're talking about on my old-old "15-speed" to get the most usable gears out of it as I could at the time. However, I didn't have nearly as many usable (for me), closely stepped gears and easily shifted gears as I have now.
For example, I now have about 17 gears starting below 1:1 with a step of less than about 14" between gears without any double shifting (except with each single change of the rings when going from low to high).

Is sliced bread actually a good thing? All of the best bread I've ever had came in unsliced loaves... ;-)
