Wow, that was a turnaround! And thank you all for the detailed analysis, especially since I have been absent and not putting in my dues here. I think I will go ahead and get the alterations done now - since I don't start my new job till the end of June.

These sleeves are actually stretchy enough that they stay scrunched both cuffed and not cuffed, but I do think the alteration will be worth it, as several have said.
