As I read your first few sentences, I was just thinking, 'sounds like the Meindl Island pro would be ideal', and then I reached your mention. Great minds think alike.
It is perhaps a bit heavy by current standards, but an excellent boot all the same.
My advice would be to go for it, particularly since you like Meindl anyway. I'm on my 4th pair, but spread over 8 years and I'm out walking nearly every weekend; I find they're pretty durable.
