I am another one who thinks that certain instruments do better with certain types of strings. For instance, I put LaBella black nylon strings on a fretless bass, and I could not play the E string without rattles. But when I put on nickel flats, the problem went away; I think it was due to higher tension. BTW, it was not that the neck bowed more with higher-tension strings, it is a graphite neck that requires no adjustment.
