I am in the same boat as you. I'm going to send in my application with 2013 pay stubs and a letter from my employer confirming my 2013 pay in lieu of the 2013 Option C printouts. For the other two years, i.e. 2011 and 2012, I will include my Option C printouts.
It is unfair for CIC to ask for Option C's for 2010, as that means they are effectively raising the bar of income requirement to 4 years instead of 3 years according to the new rules.
As soon as I get my Option C for 2013, I will send that in-before they get back to me saying me application is incomplete, which will likely take 42 months according to the current timelines.
