Brasso,
I have not had the opportunity to look thru the new EuroDiamonds, since they are not available yet, but I really like the Nikon Monarch Golds. When comparing total lenght of both scopes there in not much of difference. The Nikon Gold 2.5-10x50 is 13", where the EuroDiamond is 3-10x40 is 13.2". So you are just looking at a quarter of an inch. To me not noticeable. I personally would go with the Gold, but if you really want the Illuminated reticle than I would go with the Burris.
