Earlier quoted context omitted.
I like playing bass tuned slightly flat because I have tiny hands and it's easier to play with less tension.
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 strang…
Not at all, there are nylon wrapped strings for electric now too! [1]
