The nylon stringed guitars I've played have all felt pretty floppy. Much floppier than any other guitar including short scale axes. I think I'd enjoy a higher tension string on a classical guitar.
What a legit classical player uses and what I want out of a classical guitar are really 2 different worlds. I know some great players that use really expensive, custom privately-made strings that cost an absurd amount of money. My strings just need to provide a great (non-traditional) plugged-in sound, and be super easy to play.
a friend of mine who is a quite accomplished classical player uses extra hard tension only and swears its the only way to go
