Thank you all so much for so many (relatively varied) responses. It goes to say that flattery can sometimes be very subjective.
I like the side slit as several of you mentioned, so that design feature will certainly be kept.
Fashintern, Murph11 and Erin, I appreciate the support for #6/shorts. I get it that it probably does not look as bad as in my head, but since I still actively dislike showing my knees if at all avoidable, I will skip that look with these pants.
Gryffin, I am 3" taller than you, but with the leg length difference, it probably comes about to the same. I am sure you look excellent in your black version.
Always Trying, completely agreed that we should wear whatever length pants personally work for us, regardless of what some sources may say.
Angie, I tried the sit down test with under the knee cuff (#5), and it was perfectly fine.
Based on the majority of the votes, and some personal preferences as well, the winners are #1 and #5. I will keep the length as is, with the slit (#1), and when the mood strikes, roll them shorter (#5). If I find that I end up wearing option #5 much more often than #1, I will hem them to the length, keeping the side slit.
