10+1 Running Badly - Do You Change Your Game?

I'm experiencing a run of cold cards at the 10+1's and am wondering if the best strategy is to just stick w/a tight aggressive strategy or if I should mix things up a little.

I guess the heart of my question is this: When your regular game is getting you nowhere, is there ever a time in a low level SNG to mix things up and try to make something happen before you get into push/fold mode? I'm not talking about doing something maniacal, but rather taking a risk or two that you normally wouldn't take so that you don't end up short-stacked on the bubble w/very little fold equity.

What's happening lately is that I'm so outchipped by the time I get to the bubble that I can't get anyone to lay down a hand. I feel so ridiculously tight for not moving earlier, but my cards just don't seem playable. Since this is my first significant cold streak, I'm unsure of whether I'm doing the right thing by waiting for the bubble or if I should be moving when the blinds are smaller, but my stack is a little more imposing.
