But the thing I like about General/Further is that it's more realistic and not as abstract (as in more straight forward and practical to everyday life). But there's no way I'm doing two Maths in VCE...
This is why the enrolment numbers for them are higher than Methods. It is unnecessary for alot of people, that level of maths. But you do point out that you want to keep your options open, hence why it would be a good idea to try methods out and go from there

Absolutely - maths is definitely useful, regardless of what maths subject you pick. The problem solving skills you obtain through it can be applied to a wide range of contexts.
You should be picking subjects based on interest, in accordance with potential pre-requisite subjects for uni courses. So your choice of English + LOTE is a good one, provided they are what you are interested in!
I never used to like maths (I was okay at it.. but I stuffed around) when I was a student in high school - it was only when I was separated from my peer group and entered uni on my own that I discovered the benefits of maths + statistics as discipline areas (so much so that i'm now going to teach maths... never thought that would happen).
Do whatever you can to keep your options open, absolutely. I think you've nailed it in terms of English & at least one maths. That covers a lot of uni courses. Don't pick subjects purely for scaling reasons - as this will likely end in disaster. Interest and a determination to do well will always overpower choice purely for scaling purposes.
