Sorry to re-rail the thread, but...
I recently measured at home, and ordered singles of the closest size, one size up, and one size down, of each of these:
Bard Rochester Wide Band
Coloplast Conveen Optima
Testing them out at home, I found that one size up seems like definitely not the way to go. The closest measured size for each of these fit well in my apartment, so decided to order more of those. Went ahead and tried out the one size down on my first and second dives using a P-valve.
Dive 1 I used the one-size-down Rochester Wide Band. Manscaped what seemed like a reasonable amount, went out for a dive, it worked great on the dive, zero issues. Removal process was quite illuminating: my manscaping was not remotely sufficient -- noted! Removing was painful but not too bad. Used some soap and some EMT shears to split the cath along the top, which gave me 2 places to peel and made it a lot easier (learned that trick from a different thread on SB, cannot find it right now).
A week later, dive 2 I used the one-size-down Conveen Optima. Manscaped way more than last time. It went on easy, but the end of the thing is a lot bendier than the Rochester. Had a hard time routing the tube such that it wouldn't kink, but found a maybe-workable solution, tested it out on land and it seemed to work. Used it twice during the dive, and it was noticeably more difficult to evacuate the bladder the first time, but much easier the second time. When I was gearing down at the truck, noticed that I must have had a blowout, since undersuit was damp in that area, but dry near the seals. Confirmed in a rest room later, in fact the thing was barely stuck on there at all, wtf!
With that experience, I think removal is no longer my primary concern. How do I avoid the blow-out? Factors that come to mind:
* There probably exists a better way to route the hose. Next time I will experiment at home rather than trying to figure it out facing my truck's open door on-site.
* Is the Conveen Optima simply inferior to the Rochester? It definitely has less of a sticky patch, and is bendier in the region between where my junk ends and the hose starts, which do not seem like desirable properties in hindsight.
* I put it on at home, drove 120 miles, stopped for a fill, picked up my buddy at his place, drove to the site, set up gear, finally got in the water. All in all it was on about 4 hours prior to splash time. Is this a mistake? From some of the removal suggestions here, it sounds like I be putting it on just before the dive, not hours prior?
Anything else?

Rochester (now Bard) Widebands stick, thats why they have been the techdiver industry standard for over 25 years. Everything else is almost as good or a lot worse and you'll have to find out for yourself. I wouldn't bother.

I use Coloplast Conveen Optima catheters and never had any painful removals. They never malfunctioned either.

BTW, Some of the caths include a sizing guide on the wrapper.
