1) Does the OR become uncomfortable in hot weather? I mean does sweat form a lot between the skin and the rubber? Does it help in those cases to increase the length of the strap by one or two notches?
Not at all. I've never had any sweat problems with either my DP or OR. When it's warm my wrist swells a bit though, and the micro adjustments in the OR deployant is excellent for that. To change one hole with the DP doesn't give the same fit, which is why I have stopped using the DP and now always use the OR for a rubber strap.

2) If you had both the OR, and another type of rubber strap with no holes, do you reckon the holes actually help to let the skin breathe more? How would you rate the OR against other rubber straps? (being Breitling or another strap manufacturer)
Not really. I guess you expose the skin a bit more to the air, but no significant difference for me.

3) Do those holes on the OR large enough so that in bright sunlight the exposed skin "spots" get sun tan, while the rest of the wrist stays "white" ? I know this may sound a very weird question, and quite frankly I never thought of this, but my wife and the sales lady in my AD both brought up this subject as a potential issue with the OR strap.
I've never experienced that as a problem. I get an even white line around the wrist - not that anyone notice, as there's normally a watch there.

4) If you had both the OR, and the Diver Pro or Diver Pro II, which one do you reckon is best of those? I guess the wonderful deployant clasp that comes with the OR is now available with the Diver Pro II strap as well, so I'll need to decide which strap to order. AFAIK the classic Diver Pro is now discontinued, so it's not an option anymore.
The OR. As said earlier the adjustments are much more versatile than on the DP and I think the DPII looks a bit plain, so OR for me.

5) If you have a bracelet and a rubber strap for the same watch, what is your wearing habit? Do you wear the rubber when the temperature is relatively low (non-summer months) only, and you put the bracelet on for the hot months? Or do you wear the rubber strap all year long?
Normally I change every now and then, as my mood change. When I'm frequently swimming, the rubber stays though.

6) When a Breitling watch head is large & heavy (e.g. exceeding 100 grams), on the bracelet the watch is still in balance, since the bracelet is also heavy. But when you put it on a rubber strap, it could become "head heavy". Does it cause any issues, or you simply set the strap length via the OR deployant clasp tight enough to make the watch stay put?
Never had any issues. Both the DP and OR are more than capable of holding a heavy head.

7) Did you ever abandon the rubber "ship" ? In other words, did you ever go back to bracelet after trying to wear a watch on a rubber strap? If so, what was the reason behind your choice?
As written above, I change every now and then just as my instable mood swings.

8) Approx. how long a rubber strap lasts if you never swim with the watch? 2 years? 5 years? 10 years?
The oldest of my OR's I've had for 2 years and been rather frequently exposing it to salt water and sun. So far it doesn't show any wear or degradation.

9) How do you clean rubber straps? Just wash it with soapy water while the watch case is cleaned, rinse it with fresh water, dry it, and that's it?
Yes, I just rinse it in fresh water and wash it with soap water whenever I rinse the rest of the watch.
