Third, what gear you want, or need, depends on the individual. I'd much rather spin up a hill at 3 to 4 mph in a 20/34 gear (my touring bike's gearing) than struggle up the same hill in a 26/34 gear. I can do both...I'm fit and strong enough...but the 20/34 is a whole lot easier.
I agree as well; your observations are borne out by my experience.
If the OP wants to keep the current crankset, he could also go with a 12-36 cassette, which according to Harris Cyclery can work with a standard mountain derailleur: "
Shimano recommends that this cassette is only compatible with Shimano Shadow type rear derailleurs. We've run it successfully with a basic Deore (non-shadow design) with a longer (20mm) B-tension screw all the way in. You might have to reverse it for more adjustment."
A change from a 32 tooth to a 36 tooth cog would make a noticeable difference.
One other possibility is to swap out the 26/36/46 crankset with a mountain triple 22-32-44 crankset and stick with the 11-32 cassette.
