HELP!! - a common situation where I misplay?

[Munkster]

I often find myself in the situation below and I am unsure if the line I have been taking is correct:

- late in a 100/9 type mtt
- I have a relatively small stack (~12xbb)
- folded down to me at c/o or dealer position and dealt something like 55-99, A9-AJ, or KQ
- my image is aggressive (since I am relatively short, I usually have been pushing at least one or two times an orbit)
- the blinds are LAG (will call an allin w/ - these are my estimates, correct me if you think I am way off - kj- kq, 55-aa, a5-ak, and will reraise allin an late position standard bet with all the above range and more).
- both blinds have me covered

In the above situations, I find myself pushing most (if not all) of the time. I understand I have more than 10xbb and the pushing rule doesn't apply but I feel if I make a standard raise:
- it's very hard for me (I don't believe it's correct) to laydown to one of their allin reraises (which will happen frequently)
- when I do call an allin reraise, it's close to being a coinflip most of the time which is added volatity I don't need and would rather just push and take the blinds down
Also, I think folding/calling with these hands must be an mistake (w/o making a raise of some sort)

Alot of the points I've made are based on my intuition and I do not have any maths to back it up.

Thanks for any help in advance.

Also, what would you do with these range of hands if the blinds were unknowns?
