Two questions about full belts and Koala swimwear

Query one: It looks like quite a few experienced users have gone with full belts and moved forward. My main concern is discomfort in the balls for several reasons. A full belt could help reduce some of that. However, what are the key downsides that make a ball trap device more useful? I get the comfort angle, but specifically how does it compare? It won’t be worn around the clock; mostly evenings and nights until morning. Query two: another user brought up Koala swimwear. The items look better than the options on eBay or dhgate based on photos alone. Any firsthand accounts would be welcome. … _1099.html … _1100.html Thanks!
