Totally agree with what has been said.
I didn't do luders, so I can't really say much about it, but I know my friends who did loved it. I don't think it's needed to be a more complete leader or officer, but it's a good time.
I did Swab Summer, second make.
If you remember your life as a swab, the two makes should have had slightly different feels to them. First make is typically the "break 'em down, teach 'em the basics" while second make is take those stripped down swabs and start building them back up into 4/c cadets ready for the return of the Corps. We knowingly approached it that way (and I distinctly remember liking my first make a whole lot less than the second make when I was a swab). Either way, the swabs become your babies and you take pride or you feel frustration as you watch them grow through the next two years you both occupy CGA together.
The weight of being a cadre really hits you just before you take over.
That 2/c summer is probably the biggest "know and love your classmates" time you'll have. Swab summer, as a swab, you really only know your platoon. 4/c year, you know your fellow 4/c in your company and teammates. 3/c summer you will spend with a few of your classmates on a cutter. 3/c year is kind of weird, you know your new company, and start hanging out with 2/c you like. Finally 2/c summer rolls around, and you really start appreciating all of your classmates. Go to CATP (when I was a cadet, we all went to ATC Mobile), study ROTR, range, etc etc etc. And before all of that, you get yelled at and trained by the company commanders of TRACEN Cape May (a rewarding experience, and a small return to your first swab summer).
1/c summer is far more about your professional development, but 2/c summer is all about your development as a leader. I have a lot of great memories from that summer.
I recommend Swab Summer cadre, either first or second make. Enjoy your classmates, respect different styles and opinions, and remember that swab summer is as much about the development of the 2/c as leaders as it is swabs to be cadets. Don't be afraid to fail and learn what you can from those around (both good and bad approaches to training).
That pressure you feel as a swab summer cadre is completely appropriate. Embrace it!
