Go with the 35. I have the 25 and absolutely love it. If the 2nd focal plane would have been available a year ago in the 35 I would have gone with it. Why not have the extra magnification to use?
I have a 5-25x ATACR (3 in fact selling one) and love them. I will admit I have not shot the 7-35 however anything NF manufactures is awesome. I am faced with sell the scope or build another rifle.
I have a 7-35 F1 and I love it , the reticle or the turret both work flawless, usually when I am hunting I use sub-tensions on the reticle and use the turret when target shootin
