As the 17-55mm is a DX lense, so it will give me a true angle of 17 to 55mm but if i were to get the 17-35mm i would get an angle of 25.5-52.4mm.
That is a less than correct understanding of what DX means.
You still need to factor in the 1.5x FOVCF for your DX lenses.
i.e. both the 17-55 and 17-35 would start from a "relative focal length" of 25.5mm ...
