Ok, I'll try to simplify.

If you are talking about the first product on
this page - they are not the Xleeves. They are part of the VacADS/VacExtender.
Voilla! That should explain it.
I have no experience with the soft-thick, only the regular soft. I'd be weary of putting something that's too constricting on my penis while I sleep, and it's conceivable the thicker silicone in the soft-thick may generate a higher level of constriction.
The medium has been great for throughout the day for me. I also want to get a hard or a medium-thick for more constriction because I can see how these might stretch out after long term use. Also, the thick ones probably aid in the "visual jimmy' effect in the pantaloons.
Nothing, the xleeves cost $20
here. The starter kit has 2 xleeves + a stealth cap and tape.
I believe the stealth cap is so you can slide it UNDER the xleeve and then attach the universal harness or some light weights. (I COULD BE WRONG, AND IF SO THEN):
The other kits have some different VacX 3 caps, and it looks like some are weighted.
They are probably sold that way to try and get you to purchase VacX 3 as well.
