"If you're working hard it comes down a lot, if there's sun it comes down a lot (not common when it rains but one of the points of Paramo is it's designed for wear the whole time, not just when it's raining) ..."
It's not difficult to take a Paramo jacket off though, and I don't find my Cascada too heavy to carry if the weather turns unexpectedly warm. It's much the same weight as my old Goretex leaky sieve, but I can wear it comfortably more of the time.
A Cascada is worth considering for general walking. Mine's as good as anything else I've tried and very comfortable. The sleeve design is good - you can push it up over your elbows and keep it there, and this is surprisingly effective in cooling down, and something you can do when it's raining but warm. Opening up the front zip also cools you down a lot - I know this is obvious, but some people don't seem to realise what a difference it makes - I do that if it's warm and not very wet.
The only downsides to my Cascada jacket: a) the jacket gets rather smelly, so I have to wash it more often than I expected b) the hood really is rather warm - which is great in winter, but in summer I sometimes have to let my head get wet. This isn't a huge problem - if I get too cold, I can put the hood up and soon warm up. Usually when it rains, even in summer, it gets cool as well, so I don't find Paramo garments so hot they are unusable.
In summer I just wear a thin shirt under it, and as I said, the jacket can be removed - just because it's meant to be worn most of the time doesn't mean it has to be. Maybe sometime I'll get a wind/showerproof for those hot days.
Some of the English and Welsh MR teams are involved in rescues of climbers and cavers. We do have crags in England and Wales (some of them are small, but high enough to hurt yourself on) and there are more caves in England and in Wales than in Scotland.
I think I need to state publicly that my policy for the last 20 years has been to lend it only to people I know personally or who have been recommended to me by someone I know. This is because of both my own and my father's experience of people causing problems either with the building, or with the neighbours - it's very easy to do things which are unhelpful to some of the locals, and I really wouldn't want to annoy any of them - they're good people and some of them have been very helpful to me.
