Thanks a lot for the quick reply :)
I guess I'll just get more of the 9-42 strings to be sure I have a good stock and not risk having to wait through a whole weekend if Murphy's law strikes breaking the last string on a Saturday 5 mins after the store closing ;)
I'm as interested in finding out about technics and various possibilities as I am in actually learning to play the instrument so I'll start googling around a bit when I don't have a chance to actually play (like at work). I'll start experimenting with the strings when I'm a bit more experienced with the playing and would actually notice a difference. :)
I'm still open to suggestions if anyone knows some good websites. :D Likewise I'll post if I find something interesting. Wikipedia defn. is a good start, haven't finished up reading all the material that is there.
