2 3x12x50 Klassiks here, one on a 300WM, the other on a 30 06. I could not ask for more. Totally happy with them. I have not looked through a 2.5x10x56, but I have heard from someone who knows scopes it was the better of the two in low light by a very small margin. My 8x56 Klassik is better in low light than either of the 3x12x50's but the variables are more useful.
