Thank you both.
I had to cut a rope in half at one point due to a core shot, hence the 40- and 32-meter ropes. I actually use them fairly often for rope soloing. Trying to pack light because of tighter baggage restrictions on our intercontinental travel and because this isn't mainly a climbing trip. From thecrag.com, it looks like a lot of the routes at San Bartolo are short, but I'm not sure how accurate that info is.
Definitely I always close the system! I'm a bit paranoid about it actually, I'll tie a knot even if it's a 30-foot pitch with a 70-meter rope. I also added a little info to my profile for future reference.
