$11's vs. $22's

I'm sure this has been discussed before.. did a search but couldn't get any good results. I have heard that there isn't much of a difference in skill between the $11 and $22 games on Party. I usually play the $11's at Party and do OK (20% ROI, 41% ITM, after 130 SNGs), and the shots I've taken at the $22's have all been a bust. I feel like I'm jinxed or something at the $22's...

Is there a big jump in moving up?
