Neat! I can understand. Also like how some guitarists who sing prefer to tune to Eb. I think it's more of a sonic fit for some registers.

I've always wanted to play heavy strings, so I also explored tuning down. Imagine my surprise seeing what Dimebag Darrell was tuning to for "Floods" on 'Great Southern Trendkill' - C# F# B E G# C. I had trouble getting intonation that worked well for me, so I went ahead and got a Les Paul style Baritone. Definitely a workout, and the opposite of going lighter, but I really dig the tone it puts out. Worth the hand cramps to practice on the 27" scale.

I recently switched to nylon wrapped strings... they also have lower tension. But I mostly did it because I play a lot of americana / folk / rockabilly / blues / jazz and wanted a better slap sound.

Unfortunately they sound terrible arco so now I have to play cello when I play in my wife's orchestra. :(

[edit] it occurs to me that you're talking about electric bass... in which case nylon strings would be a bit strange ;) sorry about that.

Like the article says, just getting lighter gauge strings is just as easy and keeps you in tune. I play guitar, and the Ernie Ball Slinkys work well for me.

If electric bass (or maybe even if not) try Thomastik-Infeld strings, especially the flatwound strings.
