My turn,
I got my pro III last week, and did my first 'away' trip in it Monday/Tuesday.
I checked the forecast and decided not to take the pant liners

You'll see why in a minute.
First impressions are, the fit is good generally but the jacket could do with an adjustable waist band to make it fit perfectly, other than that, I've always riden with my trouser legs tucked in my boots, and when needed the wet weather over suit goes over them obviously to keep the wet stuff out. So putting these over the boot feels a little odd as my socks aren't long enough to reach the top and the boot 'gaiter' rubs a bit on my leg. Not a huge problem, just feels strange at the moment.
The weather did change (should have expected that) So with the liner in the jacket I set off home in the sunshine knowing that the rain was heavy at home (according to the very accurate weather report from the wife i.e. IT'S PISSING IT DOWN HERE !)
No problems in the dry, about 25 Degs C. and I didn't really feel much warmer than the previous day at similar temps and no liner. I hit the rain and for the first 20 mins no change at all inside the suit. Given the heavy rain I was quite pleased, nothing in the pants either (no liner) Then slowly I felt like I was getting wet around my inner elbows, not much but enough to think I had a leak. Then sure enough when the water did find its way down the jacket onto my legs I did get some in above the knees which the made it's way down into my water proof boots. Can't complain about that when I forgot the bloody liners
Any how, when I got home after another 30 mins or so things hadn't really gotten any worse, so other than my arms I thought the kit did a fairly good job if not quite perfect. Then when I took the jacket off I realised that, like a couple of other guys, my arms weren't wet at all just cold. The temp. had dropped to about 16 Degs. and having just a thin piece of water proof material between me and wet a jacket made me feel like I was wet
I'm sure this would be fine in warmer temps. but I've made a mental note that I'm gonna need a long sleeved top for wet weather riding.
All in all 8/10
but as I get used to the suit I may well get better results from it
(it'll probably make 9/10)
and it looks good on the bike (getting closer to 10/10)
