Extracting Max Value from big hands using aggressive image

[1outer]

This is more of a situational post, as it pertains to situatins I have been in, opposed to a few sample hands. I generally play $22 - $55 6-max SNG's. I tend to play tight in the early levels, but play aggressively postflop in hands that I am in (c-bet every flop, 3betting opponents who seem weak). So for the most part up until I get about 3 handed, I generally feel like I have a very TAG image.

Very often I find myself holding 50% of the chips on the table once it gets down to 3 handed. (9000 total, I have 4500ish and 2 opponents have remainder of chips). I used to play a very laggy style at this point, but found myself just becoming the table donator and bring stack sizes to about equal. However, I do play more aggressively and open my range of hands that I can open with in any position. I have learned how to lay a hand down tho, even with large blinds/antes making every pot a big pot.

My question is, I find myself raising 2/3 hands of every orbit and playing post flop very aggressively. I take down a lot of uncontested hands on the flop in HU pot. Because I am just running the table over, I tend to thnk that I can start getting big action with my big hands. However, I find myself time and time again flopping a full house after I have raised 3 hands in a row, betting 1/2 - 2/3 the pot and both opponents just instamucking.

I have watched lots of MTT final tables where great players lead with huge hands and get huge action. I kno my image was very TAG in the early stages, however, I have shifted gears and am playing a more LAG style. What kid of image must I build for myself inorder to be able to lead into a pot with the nuts and get paid off. I kno myself, if I find someone getting way too aggressive on his button and he leads paired board, I will 3bet and take pot away a lot of the time.
