I am kind of new here so any help you can give I am sure will help. For 25 years I have been with my 40 oz B&L discovers in 7x50,but they are now to heavy. My wife has a pair of 7x35's at 20 oz. but they are acting like the heavy 7x50's they wobble to light . I like 7 power so a 7x42 Leica ultra vid might fix the problem at 27 oz's What do you think ? And are they a good bino I have not seen much about them. I do not want to get to near 40oz again.Do you think 27oz is enough ? may be to hard for you to know anyway ,Thanks for your input.
