Glad to have found this thread.
For those using a QD, where are you placing the QD in the line? The ones I got off amazon seal when they are not attached, so unless I'm hooked up to the drysuit I wouldn't be able to pee. I could see this being problematic if I'm installing the condom cath early in the day and suiting up later in the day for diving. What's the solution for this? Different QD? Bringing an extra female bit to have when you need to go on land?
