I think I need a shorter cage with a slightly smaller base ring and shaft diameter (see attached image). Everything I’ve read says smaller is better as is it helps prevent getting hard and makes nights more comfortable. Been locked up this round by my wife 24/7 for about five days now. In past was locked up off and on for several month. Only issue now is some occasional discomfort in the wee hours of the morning (pun intended). Those with experience downsizing, has it made a difference?
