Difficulties with wearing a device? discussion

Hello everyone, I need some guidance.

Just to give you the background before we begin: I am uncut. I’m relatively new to chastity and currently own just one cage, a budget-friendly Amazon find (see pic 1). Now I’m considering purchasing the model shown in pic 2. The issue is that I’ve tested three ring sizes on my current cage—the 40mm, 45mm, and 50mm—and they all fit. This creates a dilemma for me. The 40mm feels snug; if it isn’t seated properly, it gets uncomfortable. The 45mm isn’t as tight but tends to slide down unless adjusted regularly. The 50mm avoids that tightness pain but wears out by sliding downward.

Should I choose the tighter 40 or 45 ring? My reasoning is that since a metal cage will weigh more, it might pull the device down further. Or should I stick with the comfort of the 50mm and accept the risk of slipping and potential pain in my testicles? Any help would be appreciated. Thanks, Ole. P.S. Apologies for the long post (this is my first time starting a thread).
