Verry Interesting.

                         Swarovski, Zeiss and Leica 10x42 weigh the same as 
their current 8x42 models. 
                         10x50s are much heavier.

                         After I quit the booze and took my Parkinsons pills, 
holding the 10 x bins still enough to focus wasn't a problem. Most Oz birders I 
know use 10 x 42 (Exceptions include two Poms, top birders, one uses 8x42,   
the other 7x50 for pelagics).
                         The table referred to by Dave Torr is interesting, 
confirms that 8x42 transmit more light to he eye than 10x42s. Maybe that is why 
the 8x42 suit the generally more gloomy conditions in the UK, although I have 
birded there many times and dont have a problem with the 10x.

                          The harness is a good idea. Waning vision is bad 
enough, developing a hunch back  (? "binocular back" ) as well would be 

                          Thankyou all for your replies, obviously the go is to 
test them out at a local bino store then import the best at huge savings from 
California. Unless the locals will deal of course.

                                                               Insincerely yours
