Full Belts discussion

Greetings everyone! I could use some guidance from the group. My spouse and I are intrigued by the prospect of a full belt. We currently own a CB-6000, which we experiment with roughly once a month for about 5 to 10 days at a stretch. It’s decent overall, but the ability to pull out is something I appreciate, along with how it tugs on my balls in the morning and during partial erections.

So, we’ve been shopping around and are thinking about trying a My-steel total system, but I figured I’d ask here for opinions or recommendations from you enthusiasts. Here are my main concerns/questions:

1. Prioritizing comfort; something suitable for 1 week to a month without trouble.
2. I feel like I want one with a tube. What are the pros and cons?
3. This might seem silly… but where do your testicles end up? Are they just pressed against you, or do the shields create a cup that holds them slightly away from the body?
4. Something with slight adjustability, perhaps an inch or two.
5. Ideally staying in the 700-900 US$ range with reasonable shipping times. I really want to avoid waiting 6-8 weeks like some sites advertise.

Thanks everyone!
