What do people think of the Berghaus Munro rucksack?

Waves of nostalgia! I used one for years until it got abandoned in Mexico - (long story).
Toughest sack I've owned, a real workhorse. It is very basic though compared to more recent designs round the same price. I do recall sweaty back syndrome in the summer and the waist belt had no padding.
I wouldn't swap back from my Freeflow 30+6 though, even if it was a bit lighter.
