I am choosing further maths over specialists as it will not take as much time and it will be much easier for me.
I'm thinking of dropping physics for MUEP or UMEP to add as my 6th subject.
personally i'm of the opinion that if you don't want to do spech (regardless of whatever the requirements to do UMEP/MUEP are) because you think further is going to be easier or because it's going to take less time then you should be reconsidering doing uni maths in the first place.
again, you really haven't said why you want to do uni maths in the first place so that would be able to help others give you more personalized feedback.
Doing uni maths was one of the best choices i made, but it isn't just something you you jump into for the hell of it.
Personally if you're choosing to do further over spech then there's two reasons for that:
1) You think spech is too hard and will hence will take up too much time (in which case i don't know why you you would want to do uni maths as uni maths is conceptually a pretty big step up from spech which is already a step up from methods)
2) You want an easier high score (again, i don't know why you would want to do uni maths, it can only count as a 5th or 6th, uni subjects aren't something you do for the score, it's something you do because you genuinely enjoy the subject and want to further you knowledge. If a high score is what you want you would be better off dedicating that time to get a higher score in your primary subjects)
Uni maths is an awesome program, i wish more ppl would do it but i'll be the first to acknowledge in terms of boosting your atar it probably doesn't correlate to the effort required and unfortunately this turns ppl off, but i wholeheartedly encourage anyone that has a passion for maths to do it (if you have the passion you will cope with the course) but it isn't for everybody.
