Round Versus Oval Base Rings

I need some feedback. I’m about to place my order for an MM Jailbird. Right now, I’m wearing a CB6000S with a 1-7/8 base ring. Lately, when we take it off, we leave the pieces connected and reapply them using the same method we plan to use for the Jailbird. Removing it isn’t difficult at all. Putting it back on is slightly harder but still manageable. We tried switching to a 1-3/4 ring, but I can’t get my second ball through it. Oh, we probably could force it, but it would hurt. I’m curious if choosing the oval ring changes things for me. According to MM, the 1-3/4 oval ring measures roughly 1 7/8 wide by 1 5/8 tall. Since I don’t have a good way to simulate that exact size at home, I wasn’t sure if I’d fit into it or should just stick with my current 1 7/8 round base ring. I’m very comfortable in the round one currently. I know the oval is supposed to offer much better comfort, but honestly, I have no issue with the round version. Any thoughts would be appreciated.
