Mature Metal discussion

Hi everyone:) I am getting ready to buy my first metal chastity device, and I have chosen the Jail Bird. The one thing keeping me up at night is the size; any advice would be welcome. The length is currently what has me torn between 2 3/4” and 3”. After measuring myself multiple times and accounting for a quarter-inch deduction, my measurements land right in that gap. My current CB3000 fits nicely with its tightest setting and feels full enough to suggest the 3” option might work. However, because of the price difference, I want some opinions here. The 2 3/4” is appealing, but I am hesitant. I have worn a cb6000s (measuring about 2.5”) before; it was wearable but felt slightly too small to me. What do you all think? Also worth noting: I am uncircumcised. Will a snug fit cause any skin pinching issues? Beyond the length, I am leaning towards a 2” base ring with a 1 1/2” cage diameter (which matches my CB3000 and seems like a solid pick) along with 3/8 spacing. I plan to choose oval rings and perhaps double them up. Thanks in advance.
