Trying to decide between these 4 harnesses for TAG pit bouncing and as I get into more complex portions of horizontal caves. Input from more experienced people than myself would be great!

Edit: I am of an average build, looking for something that won't ride up to my nipples when I am frogging up the rope, and that will be comfortable and durable.

I need to get a bunch of carabiners for my training to do more vertical caves. I'm thinking of getting around 50+ biners, several friends want a large number as well. A total of 200-400. With such a volume, can anyone recommend a supplier that offers wholesale volume pricing? Also will be looking for slings, quickdraws, etc.

I'm working on restoring a 1982 Yamaha XJ650J Maxim. As of right now, when I turn it on or start it, the center taillight comes on, but the headlight (low and high beams) does not. When I turn on the turn signals, I either get no reaction or 3 of the 4 lights come on. As in both front turn signals and 1 rear. Is this likely to be a switch issue? Relay? Diode pack? What are the common electrical issues with these things? Any input would be appreciated.

How do I tell the difference between the XJ650J and XJ650RJ, or Maxim/Seca? I just bought one as a project bike, and trying to figure out what is original to it.

I have had my E3Pro for about 2 weeks. It is my first 3D printer and I've been excited. When I came home from work yesterday, I found that the menus looked different from the usual. Now it says that I have Marlin 1.0.6 instead of 2.0.x and nothing seems to operate correctly. Even the motors are not working properly. Has anyone had this happen to them and if so, how would I go about resolving it?

Edit. It appears that somehow the firmware reverted to an earlier version that is not compatible with this printer. I have tried copying the bin files to an empty microsd card, putting it in the printer and then powering on, but no change. Any help would be appreciated.

Edit 2: Figured out that for

Only a couple layers of skin were burned, it has been about a week since it happened, there is no bleeding or oozing, just dry skin and sensitivity. On the one hand, saliva is supposed to have some healing properties, but on the other hand it is supposes to have some level of acidity to begin digestion as you are chewing your food. So is it a bad idea to receive fellatio at this time, or should I let my SO do it and relax?
