Well I feel like the fact that you bought 6 says pretty decent things about them haha. I'm just far enough out of Sydney that a trip down there is too much of a pain, plus it sounds like the returns policy is generous enough that I'll be able to send it back if I'm not happy. However I did just get an email back saying that they do have a fatter neck, so from that it sounds like it should be ok.
I am also considering the modded strat idea too, if I come across something then that would be viable for sure.
WAIT! WAIT! There was an excellent Pink Bullet Strat at a Pawn shop nearby! I might have to look at that and see if it's still there!!
