Thank you all who replied - I am now seriously considering spending a few extra dollars to get the H2O for its added ruggedness - I am not the clumsiest person on the planet, but I have been known to drop a thing on occasion.
Complexity does not scare me in the least - in fact it lets my geeky mind explore new terrain in much the same way as seeking a cache will involve me. Think of it, two opportunities for discovery in one place!
Well, when I say 'considering spending,' I really mean 'considering convincing my wife to spend a few extra dollars on my birthday present.' With a little luck, I will soon be searching nearby areas for hidden treasure.
Regards
