Stretching Mirage Swift LT?

I have a Mirage Swift LT and the S pillow is a bit too small and the M pillow is much too large. Even more complicated, one of my nares is noticeably bigger than the other. Has anyone tried stretching the material the pillows are made with, to make one nare bigger? If so, how did you do it, how much pressure did you use?

Thanks!

They won't keep their size if stretched (silicon material properties) and if over stretched will more likely rip ... if you must err on size of nasal pillows, err on the side of larger rather than smaller.

You might try this link for ideas:

That is a great link for modifying the Swift LT to increase airflow BJ. I think Digi's issue is a bit different and is trying to get two different size pillows.

I forgot to mention that the Breeze mask allows one to mix and match pillow sizes but the headgear for the Breeze is not well like by some. If you decide you can use something like the Hybrid or Liberty, those also are capable of mix and match pillow sizes for folks with different size nares.
