Thanks for the replies everyone.
Sunday's weather was exceptionally bad but I'm sure we all look for kit to be 100% waterproof especially when high up at cooler times of the year.
For most of the surface of the jacket the Paramo system worked well enough, so thinner material is not the issue. The cuffs are a weak point, in addition to the pressure points. There is a small internal storm flap but insufficient in this case to keep out driving rain. Probably, for me, the greatest weakness is the shortness of the jacket combined with it extending to just below my rucksack belt.I did originally consider getting a Velez but they also are short on me unless I go for the large size which is very baggy.
My Alta jacket, worn in cold weather, has never been subjected to the same amount of rain (now that the summer seems to be the wettest seasion of the year) so I'll reserve final judgementuntil I wear that in heavey rain.
